Collocations & Phrasal Verbs - Adult ESL ELL Advanced

  1. A graduate student is revising a research proposal and wants to replace informal language with more formal equivalents. She identifies the phrasal verb "figure out" in the sentence: "The study aims to figure out the underlying causes of urban migration." She considers four replacements. Which replacement is MOST problematic because it changes the meaning of the original sentence rather than simply elevating the register?
    Answer: Replace "figure out" with "investigate," which changes the meaning from arriving at an answer or solution to merely conducting a process of examination — removing the implication that the research will reach a conclusion, which is central to the original sentence's claim. When revising for academic register, your goal is to elevate tone without altering meaning. The trap this question tests is assuming any formal word can replace an informal one — but synonyms exist on a spectrum, and some carry different semantic weight than others. "Figure out" means to arrive at an answer through active investigation — it implies both a process and a result. The replacement that causes the most damage is C: "investigate." While "investigate" sounds academic, it describes only the process of examining something, with no implication that a conclusion will be reached. The original sentence makes a claim about what the study will accomplish (reaching an understanding of causes), and replacing "figure out" with "investigate" strips away that promised outcome entirely. That's a meaningful change, not just a stylistic one. Choice A is a reasonable concern — "ascertain" does carry a subtle nuance of confirming suspected information — but this shift is minor and context-dependent. In many academic contexts, "ascertain" still functions as a near-synonym for "figure out." Choice B ("determine") is actually the strongest replacement: it preserves both the process and the conclusion-reaching meaning while fitting naturally in formal prose, which is why it's presented as clearly correct within the option itself. Choice D raises a fair point about "identify," but the explanation within that option honestly acknowledges that "identify" is conventionally accepted in research writing to mean discovering and naming something — so the shift is subtle enough not to be disqualifying. Strategy tip: When evaluating synonyms in register-shift questions, ask yourself two things: Does the new word preserve the process? Does it preserve the outcome? If either is missing, the substitution changes meaning rather than just formality.
  2. A student studying English collocation patterns notices that the verb "run" appears in several phrasal verbs with very different meanings. She creates the sentence: "After the funding ran out, the project committee decided to run through the remaining options before agreeing to run up additional debt." She asks her instructor whether the three uses of "run" are all phrasal verbs and whether they are all informal. Which answer is most accurate?
    Answer: All three are phrasal verbs: "ran out" (to be exhausted or depleted), "run through" (to review), and "run up" (to accumulate, as in debt) — and none of the three is inherently informal, since all three appear regularly in formal professional, journalistic, and business writing without requiring replacement. When analyzing phrasal verbs, you need to consider two separate questions: grammatical classification and register (formality level). These are independent features — a verb phrase can be a true phrasal verb and still be perfectly acceptable in formal writing. All three expressions — "ran out," "run through," and "run up" — qualify as phrasal verbs because in each case, the particle combines with "run" to create a meaning that cannot be predicted from the individual words alone. "Ran out" means depleted, not physically exited; "run through" means to review, not to physically pass through something; "run up" means to accumulate, not to ascend. This idiomatic shift in meaning is the defining feature of a phrasal verb. Answer A correctly identifies all three as phrasal verbs and, crucially, notes that none is inherently informal — all three appear routinely in business reports, financial journalism, and professional correspondence without sounding out of place. Answer B makes the common mistake of assuming phrasal verbs are automatically informal. This is a widespread myth, but register depends on context and frequency in formal usage, not on whether a verb has a particle attached. Answer C incorrectly claims "run through" is a prepositional verb because "through" retains spatial meaning — but the meaning here is clearly figurative and idiomatic, not directional, which keeps it in phrasal verb territory. Answer D invents a false rule: separability has no consistent relationship with formality level in English. Your study tip: never automatically flag a phrasal verb as informal. Always ask whether educated writers use it in professional contexts — if yes, it's register-neutral.
  3. Which sentence contains a collocation error, and what is the most precise linguistic explanation for why it is an error?
    Answer: Sentence 2 contains the error: "made a strong emphasis" is incorrect because "emphasis" collocates with "placed" or "put," not "made," and while "strong" can modify emphasis semantically, the verb-noun collocation is conventionally fixed and cannot be substituted based on meaning alone. Collocations are fixed word partnerships that native speakers use instinctively — they can't always be explained by logic or grammar rules alone. When a question asks specifically about collocation errors, your job is to identify which combination violates conventional word pairing, not which sentence sounds odd for stylistic reasons. The error in this set lives in Sentence 2. In English, "emphasis" collocates with the verbs "place" or "put" — native speakers say "put emphasis on" or "place emphasis on." Using "made" with "emphasis" breaks this conventional pairing. Notice that the error isn't semantic: "strong" meaningfully describes emphasis, and "made" grammatically fits the slot. But collocations are not determined by meaning or grammar alone — they're determined by usage convention. You cannot simply swap in a synonym for the collocating verb and expect the phrase to work. This is precisely why A is correct. B is wrong because "gave a speech" is a fully standard and accepted collocation in both formal and informal registers — not an informal shortcut. "Delivered a speech" is also correct, but "gave" is not an error. C is wrong because "took a look" is a legitimate, widely accepted collocation in English; "had a look" is also correct, but both are conventional — no violation exists. D is wrong because "held a debate" is perfectly standard; "held" collocates naturally with organized events including debates, conferences, and discussions. As a study strategy, remember: collocation questions test convention, not logic. If a phrase sounds natural to fluent speakers and appears consistently in published writing, it's likely correct — even if a synonym seems equally reasonable.
  4. The professor asks students to identify which sentence(s) contain non-standard collocations — meaning native English speakers would typically use a different verb — and to explain the pattern. Which answer best identifies the non-standard usage(s) and explains the underlying collocation principle?
    Answer: Sentence (C) is non-standard: native speakers would say "gave a presentation" rather than "did a presentation." Sentences (A), (B), and (D) are all standard because "do" conventionally collocates with "homework," "research," and "check" — the underlying pattern is that "do" applies to tasks and processes, while "give" is required when an action involves a performance or delivery before an audience. Verb-noun collocations are fixed pairings that native speakers use naturally — the "wrong" verb isn't always grammatically incorrect, but it sounds unnatural because English has established preferred combinations. When you see "do" paired with a noun, ask yourself: is this the verb a native speaker would actually choose? Answer D correctly identifies that "do" has legitimate, established collocations with "homework," "research," and "check" — these are task- or process-oriented nouns where "do" is genuinely standard. The non-standard sentence is (C): native speakers say "gave a presentation," not "did a presentation." The underlying principle is meaningful: "give" is required when an action involves delivering or performing something for an audience — a speech, a talk, a presentation, a tour. "Do," by contrast, applies to tasks you complete, processes you carry out, or work you perform independently. Answer A overstates the case dramatically. "Did her homework" is perfectly standard English — even in formal contexts, "do homework" is the native collocation. Claiming all four sentences are non-standard misrepresents how collocations actually work. Answer B correctly flags (C) but wrongly targets (B) — "do research" is fully acceptable and widely used alongside "conduct research"; the two co-exist, and "do" is not deficient here. Answer C introduces a false grammatical rule: adjective modification does not trigger a mandatory verb change. "Did a thorough check" sounds natural to most native speakers, making this distractor particularly misleading. Your strategy: memorize collocations as fixed chunks. For "give," focus on audience-directed actions — give a speech, give a presentation, give a tour. For "do," think tasks and processes — do research, do homework, do a check.
  5. The email contains one collocation error that a native-speaking admissions reader would immediately notice as unnatural. Which underlined verb-noun pair is the error, and which replacement most precisely corrects the collocation?
    Answer: "making new challenges" is the error; the conventional collocation is "taking on new challenges" or "embracing new challenges," because "challenge" collocates with verbs such as "face," "meet," "take on," or "embrace" — not "make," which implies creation rather than encountering or accepting a difficulty. Collocation questions test your knowledge of fixed verb-noun pairings in English — combinations that native speakers use automatically, even when alternative words seem logically equivalent. When evaluating an email like this, read each underlined pair and ask: would a native speaker naturally say this? The clearest error is "making new challenges." In English, "challenge" pairs with verbs that express encountering or accepting a difficulty: face, meet, take on, or embrace. Using "make" implies you are creating a challenge for others, which is the opposite of what the writer intends. A native reader would immediately pause at this phrase — making C the correct answer. The distractors are tempting but each contains a flaw. Answer A argues that "achieved significant progress" is wrong, but this is actually a defensible collocational choice. While "made progress" is more conventional, "achieved progress" is not jarring to a native reader in the way that "making challenges" is. A targets a subtler preference, not a clear error. Answer B raises a fair point — "done several projects" is informal — but "do a project" is genuinely common in both American and British English and would not immediately signal a non-native writer. It reads as casual, not wrong. Answer D claims "gain knowledge" carries a commercial connotation and that "acquire" is more scholarly. While "acquire" is slightly more formal, "gain knowledge" is a well-established, natural collocation that appears frequently in academic writing and would not strike an admissions reader as an error. When studying collocations, keep a running list of verbs that pair with common abstract nouns: make progress/an effort/a decision, take on challenges/responsibilities, achieve goals/results. These fixed patterns are where non-native writers most often slip.
  6. Which sentence contains an incorrect collocation, and what is the most precise reason it is wrong?
    Answer: Sentence (iii) is incorrect: "reached a unanimous conclusion" is a collocation error because "conclusion" conventionally collocates with "drew" or "came to" — the verb "reach" is standard with "agreement," "consensus," or "settlement," but not with "conclusion," where it violates the fixed verb-noun pairing that native speakers observe. Collocations are fixed word partnerships that native speakers use automatically — they sound "right" without a rule to justify them. When a question asks you to spot a collocation error, resist the urge to focus on formality or register; instead, ask yourself whether the specific verb-noun pairing actually exists in standard educated usage. The error is in sentence (iii). In English, "conclusion" pairs naturally with "drew" (as in "drew a conclusion") or "came to" (as in "came to a conclusion"). The verb "reach," while close in meaning, conventionally pairs with words like "agreement," "consensus," "settlement," or "decision" — not "conclusion." A native speaker would instinctively say the board drew or came to a unanimous conclusion, making "reached a unanimous conclusion" the odd pairing out. Answer A identifies this correctly and for precisely the right reason. The other answers each commit a different kind of error. Answer B incorrectly claims "conducted a survey" is wrong — in fact, "conduct a survey" is a perfectly standard collocation used widely in academic writing, including literature reviews; the verb is not restricted to experiments. Answer C argues that "made a compelling argument" is too informal for academic writing, but this is false — "make an argument" is completely standard and widely used in formal and scholarly contexts. Answer D suggests "take legal action" is too generic and informal, but this phrase is a fully established legal collocation that appears regularly in professional and formal legal documents. Your study tip: when evaluating collocations, don't let tone or formality mislead you. Focus narrowly on whether the verb and noun actually pair together in standard usage — that's the only test that matters here.
  7. An advanced ESL student is proofreading a formal business report and encounters the following sentence: "The marketing team will look into the declining sales figures and come up with a viable strategy before the fiscal quarter ends." The student's professor marks the sentence and writes: "Consider register." Which analysis of the sentence's register issue is most accurate?
    Answer: "Look into" is neutral in register and acceptable in formal business writing, but "come up with" is informal and should be replaced with "develop," "formulate," or "devise," since "come up with" carries a casual, conversational tone that is inconsistent with the formal register expected in professional reports. When you encounter a question about register in formal writing, your job is to assess whether the vocabulary choices match the expected tone and context — in this case, a professional business report demanding formal, precise language. Phrasal verbs are verb phrases made up of a verb plus a particle (like "look into" or "come up with"). In English, they often carry an informal or conversational tone. However, not all phrasal verbs carry the same level of informality, and that distinction is exactly what this question tests. Answer B is correct because the two phrasal verbs actually sit at different register levels. "Look into" is relatively neutral — it appears comfortably in both formal and informal contexts without sounding out of place in a professional document. "Come up with," however, carries a distinctly casual, improvisational feel. In a business report, you would replace it with something like "develop," "formulate," or "devise" to match the expected professional tone. Answer A goes too far by treating both phrasal verbs as equally informal. This is the most common trap here — overgeneralizing the rule that "phrasal verbs are always informal." Register operates on a spectrum, not a binary. Answer C flips the assessment entirely, misidentifying "look into" as the problematic phrase while excusing "come up with" by calling it a technical collocation. "Come up with" has no specialized technical meaning in project management — this reasoning is invented. Answer D dismisses the register concern entirely, which ignores a real and identifiable issue in the sentence. Your takeaway: not all phrasal verbs are equally informal. When analyzing register, evaluate each phrase individually rather than applying a blanket rule.
  8. A language instructor is teaching the distinction between separable and inseparable phrasal verbs and their register implications. A student claims: "All separable phrasal verbs can have a pronoun inserted between the verb and the particle, and all of them are informal, so they should always be replaced with single-word verbs in formal writing." Which response MOST accurately addresses the errors in the student's claim?
    Answer: The student conflates two independent properties: separability means a pronoun object must be placed between the verb and particle (e.g., 'turn it off,' not 'turn off it'), but this syntactic feature has no bearing on register — many phrasal verbs, both separable and inseparable, are neutral or formal in tone and entirely appropriate in professional and academic discourse. When analyzing claims about phrasal verbs, you need to evaluate two completely separate dimensions: syntax (how the verb behaves grammatically) and register (how formal or informal it sounds). The student's mistake is treating these as linked — they aren't. Separability is purely a syntactic property. A separable phrasal verb requires a pronoun object to appear between the verb and particle — you must say "turn it off," never "turn off it." However, this grammatical behavior tells you absolutely nothing about formality. Phrasal verbs like carry out, set up, or point out appear regularly in academic and professional writing without any stylistic problem. Register depends on the specific verb, its context, and the discourse community — not on whether it's separable or inseparable. Answer D captures both points precisely: separability governs pronoun placement, and that syntactic fact is entirely independent of register. Answer A partially corrects the student by acknowledging that some phrasal verbs suit formal contexts, but it accepts the false claim that pronoun insertion is obligatory only with separable verbs — it already is, so that "correction" is confused. Answer B contains a serious error: it claims replacing phrasal verbs with Latinate equivalents is "best practice" in most style guides, which is false — overusing Latinate vocabulary is frequently criticized as unnecessarily stiff. Answer C accepts the student's incorrect claim that separable phrasal verbs are "generally informal," which oversimplifies the relationship between form and register. As a study strategy, whenever you see claims that bundle a grammatical rule with a stylistic judgment, slow down and ask yourself: are these actually connected, or is the question testing whether you can separate them?
  9. The paragraph contains collocation and phrasal verb errors. Which of the following correctly identifies ALL the errors and provides accurate replacements?
    Answer: "make a thorough research" should be "conduct thorough research," "do a decision" should be "make a decision," and "strong a compromise" should be "reach a compromise" — three errors in total, while "put off" is used correctly as a separable phrasal verb meaning to postpone, which is neutral in register. When editing academic writing, you need to evaluate two things simultaneously: whether phrasal verbs and collocations are used correctly, and whether claims about grammar rules are themselves accurate. This question tests both skills at once. The passage contains three genuine errors. "Make a thorough research" is wrong because "research" is an uncountable noun — the correct collocation is "conduct thorough research" (or "do research," but never "make research"). "Do a decision" is wrong because the fixed collocation in English is "make a decision." "Strong a compromise" is simply not a recognized English phrase — the correct collocation is "reach a compromise." Meanwhile, "put off" meaning "to postpone" is a perfectly standard phrasal verb, correctly used here. Answer A identifies all three errors accurately and makes no false claims about grammar — making it correct. Answer B is wrong on two counts: it incorrectly flags "put off" as an error and falsely claims "strong a compromise" is acceptable formal phrasing. Neither is true. Answer C is wrong because it suggests replacing "make a thorough research" with "do thorough research" — while "do research" is grammatically possible, the explanation then undermines itself by calling this correction "non-standard," which creates confusion rather than clarity. Answer D makes a categorical claim that phrasal verbs are always inappropriate in formal academic writing — this is simply false. Many phrasal verbs ("carry out," "set up," "put off") are neutral or acceptable in formal contexts depending on register. Your study tip: never trust an answer that makes an absolute rule about English — phrases like "always" or "categorically inappropriate" are red flags on language exams.
  10. The student's professor comments that the paragraph mixes registers inappropriately for academic writing. Which assessment of the phrasal verbs is most accurate in terms of register appropriateness?
    Answer: "Rooted in," "held back by," and "built up" are appropriate for academic writing because they function as fixed collocations or neutral passive constructions with no informal connotation; "brush off" and "throwing away" are informal and should be replaced with "dismiss" and "discarding" respectively to achieve consistent academic register throughout the paragraph. When answering register questions, your job is to evaluate each word or phrase individually — not assume that an entire grammatical category (like phrasal verbs) is uniformly formal or informal. Register is about how a specific expression is actually used in professional and academic contexts, not about its surface structure. In this paragraph, the five phrasal verbs have very different register profiles. "Rooted in" is a well-established academic collocation — you'll find it regularly in peer-reviewed journals (e.g., "rooted in critical theory"). "Held back by" in a passive construction functions neutrally and appears in scholarly writing without sounding casual. "Built up" in the sense of "accumulated over time" is similarly neutral and common in academic prose. These three require no revision. However, "brush off" carries a distinctly conversational, dismissive tone — it belongs in everyday speech, not scholarly argument. Likewise, "throwing away" reads as informal when alternatives like "discarding" or "abandoning" are available and more precise. Replacing both with formal equivalents corrects the register inconsistency, which makes B the accurate assessment. Answer A fails because it treats all phrasal verbs as inherently informal — a false rule. Academic writing uses many multi-word verb constructions regularly; the issue is connotation, not grammar. Answer C goes too far in the opposite direction, claiming only "brush off" needs revision while letting "throwing away" pass — but "throwing away" in this context is colloquial and weakens the scholarly tone. Answer D incorrectly marks "built up" as informal (it's neutral here) and incorrectly defends "throwing away" as acceptable when used metaphorically — metaphorical use doesn't automatically elevate a phrase's register. Your strategy: when evaluating register, ask yourself where you'd expect to see this phrase — in a text message or in a journal article? That mental test quickly separates informal from academic expressions.
