FRENCH 2 • LANGUAGE SYSTEMS (GRAMMAR & SYNTAX)

Making Comparisons — I can use comparisons (plus/moins/aussi) to describe preferences and evaluate options.

Master the structures of plus, moins, and aussi to compare people, things, and ideas in French.

Historical Context & Motivation

Humans have always needed to compare things — deciding which food is better, which path is shorter, or which leader is stronger. In language, comparative structures evolved to express these judgments efficiently. French inherited its comparative system from Latin, the language of the Roman Empire, which used special word endings (suffixes like -ior) to form comparisons. Over centuries, as Latin transformed into Old French and then Modern French, these suffixes disappeared and were replaced by separate adverbs placed before adjectives and adverbs.

100 BCE
Latin Comparative Suffixes
Latin used synthetic comparatives: fortis (strong) became fortior (stronger). No extra words were needed — the comparison was built into the adjective itself.
900 CE
Old French Transition
As Vulgar Latin evolved into Old French, speakers began using the word plus (from Latin plūs) before adjectives, gradually replacing the old suffixes.
1500s
Modern French Solidifies
By the Renaissance, the system of plus / moins / aussi + adjective/adverb + que became standard in written and spoken French.
1600s
Académie française Codifies Grammar
The founding of the Académie française in 1635 formalized grammar rules, including comparatives and superlatives, setting the standard still taught today.

Understanding this history helps explain why French uses separate words for comparison instead of changing word endings the way Latin did. English, by contrast, uses a mix of both strategies — you say "taller" (suffix) but "more interesting" (separate word). French is more consistent: it almost always uses plus, moins, or aussi before the describing word. The central question this lesson addresses is: how do you build and use these comparative structures to express preferences, evaluate options, and communicate your opinions clearly in French?

Core Principles of French Comparisons

French comparisons follow a predictable pattern built from three key adverbs. Once you learn the formula, you can compare virtually anything — people, objects, experiences, and abstract qualities. The core structure is: comparison word + adjective/adverb + que + the second element. Let's break down the foundational ideas that make this system work.

1

Plus … que (more … than)

Expresses superiority — one item has MORE of a quality. Example: Paris est plus grand que Lyon. (Paris is bigger than Lyon.)
2

Moins … que (less … than)

Expresses inferiority — one item has LESS of a quality. Example: Le bus est moins rapide que le train. (The bus is less fast than the train.)
3

Aussi … que (as … as)

Expresses equality — both items share the SAME degree. Example: Marie est aussi intelligente que Paul. (Marie is as smart as Paul.)
4

Adjective Agreement Still Applies

The adjective must still agree in gender and number with the first noun being described. Plus, moins, and aussi never change form.
5

Irregular Comparatives Exist

A few adjectives have irregular comparative forms. Bon (good) becomes meilleur (better), and mauvais (bad) can become pire (worse).
KEY TAKEAWAY
Think of comparisons in French like a sandwich: the comparison word (plus, moins, aussi) is the top slice of bread, the adjective or adverb is the filling in the middle, and que is the bottom slice. Whatever you're comparing to comes after que. Just like you can't have a sandwich without both slices, you need both the comparison word and que to complete the structure.

Visual Explanation: The Comparison Formula

This diagram shows the three comparison patterns side by side. Notice that the structure is identical in all three — only the comparison word (plus, moins, or aussi) changes. The adjective sits in the middle, que acts as the bridge, and the second element completes the comparison.

As you can see from the diagram, the three comparison types share an identical skeleton. This means you only need to learn one pattern and then swap out the first word depending on your meaning. If you want to say something has more of a quality, use plus; less of a quality, use moins; and the same amount of a quality, use aussi. The word que (meaning "than" or "as") is always required to introduce the second thing you are comparing.

How the Comparison System Works in Detail

Comparing with Adjectives

When you compare with adjectives, the adjective must agree in gender and number with the first noun — the subject of the sentence. The comparison words (plus, moins, aussi) themselves never change form. Consider these examples: Sophie est plus grande que Marc. Here, grande is feminine singular to match Sophie. If we compared two feminine plural subjects, we would write: Les filles sont plus grandes que les garçons.

Comparing with Adverbs

Adverbs describe how something is done, and they are invariable — they never change form for agreement. The comparison structure remains the same. For instance: Elle parle plus vite que moi. (She speaks faster than me.) Notice that vite does not change regardless of the subject. Another example: Il travaille moins souvent que toi. (He works less often than you.)

Comparing with Nouns (Quantities)

When comparing quantities of nouns, the formula changes slightly. Instead of an adjective, you use plus de / moins de / autant de + noun + que. Notice that for equality with nouns, you use autant de (not aussi). Example: J'ai plus de livres que toi. (I have more books than you.) Or: Elle a autant d'amis que lui. (She has as many friends as him.)

Comparing with Verbs (Actions)

You can also compare actions using verbs. The pattern is: verb + plus / moins / autant + que. Again, for equality with verbs, use autant (without de). Example: Je mange plus que mon frère. (I eat more than my brother.) Or: Tu étudies autant que moi. (You study as much as me.)

⚠️ Watch Out!
A very common mistake is using aussi when comparing nouns or verbs. Remember: aussi is ONLY for adjectives and adverbs. For nouns, use autant de; for verbs, use autant.

Irregular Comparatives & Special Cases

Just as English has irregular comparatives ("good" → "better," not "more good"), French has a few adjectives and adverbs that break the regular pattern. These irregular forms are among the most commonly used words in the language, so learning them is essential.

The three most important irregular comparatives in French. Note that meilleur is an adjective (modifies nouns), while mieux is an adverb (modifies verbs). Never say "plus bon" or "plus bien" — these are considered incorrect in standard French.

There is a subtlety worth noting with mauvais. Unlike bon, the word mauvais can actually be used with plus in some contexts. You might hear plus mauvais in informal speech, and it is considered acceptable. However, pire is generally preferred in formal writing and is more elegant. On the other hand, plus bon is almost universally avoided — always use meilleur instead.

mal — badlyadverbpis / plus malIl dort plus mal que sa sœur.

Worked Example: Comparing Two Vacation Options

Imagine you are writing an email to a French exchange student, comparing two vacation destinations — Nice and Bretagne — to decide where to go this summer. You want to compare the weather, the food, the cost, and the activities. Let's build the comparisons step by step.

Comparing Nice and Bretagne
1
Step 1 — Identify What You're ComparingWe are comparing two destinations: Nice (on the Mediterranean coast) and la Bretagne (in northwestern France). We need qualities to compare: weather (chaud — warm), food (bon — good), cost (cher — expensive), and fun (amusant — fun).
2
Step 2 — Choose the Comparison TypeFor weather, Nice is warmer → superiority → plus. For food, both are equally good → equality → aussi (but watch out — bon is irregular!). For cost, Bretagne is less expensive → inferiority → moins. For fun, you think they are equally fun → equality → aussi.
3
Step 3 — Apply Adjective AgreementNice is a feminine city name (la ville de Nice), and Bretagne is also feminine (la Bretagne). Since we are comparing weather/food in general terms, the adjectives typically match the subject noun. La cuisine is feminine, so bonbonne → but wait, bon is irregular in comparisons! We use aussi bonne for equality (irregular forms only apply to superiority comparatives).
4
Step 4 — Construct the SentencesNow we assemble each comparison using the formula: comparison word + adjective + que + second element.
1. Nice est plus chaud que la Bretagne. (Nice is warmer than Brittany.) 2. La cuisine de Nice est aussi bonne que la cuisine bretonne. (The food in Nice is as good as Breton food.) 3. La Bretagne est moins chère que Nice. (Brittany is less expensive than Nice.) 4. La Bretagne est aussi amusante que Nice. (Brittany is as fun as Nice.)
5
Step 5 — Express a PreferenceTo wrap up your comparison, you can express a preference using Je préfère… or J'aime mieux… combined with your comparisons.
Je préfère la Bretagne parce qu'elle est moins chère et aussi amusante que Nice ! (I prefer Brittany because it's less expensive and as fun as Nice!)

Common Pitfalls & Strengths of the System

French comparisons are beautifully systematic, but certain traps catch learners regularly. Understanding these pitfalls in advance will save you from making errors on assignments, essays, and in conversation. The table below contrasts the strengths of the French comparison system with the most common mistakes students make.

Strengths vs. Common Pitfalls in French Comparisons
StrengthCommon PitfallHow to Avoid It
One formula works for almost all adjectives and adverbsForgetting to use irregular forms (saying "plus bon" instead of "meilleur")Memorize the four irregulars: meilleur, pire, mieux, pis. Flashcards help!
The comparison word never changes form (no conjugation or agreement)Forgetting adjective agreement (saying "plus grand" when subject is feminine)Always check the gender/number of the FIRST noun and adjust the adjective accordingly.
Clear distinction between adjective, adverb, noun, and verb comparisonsUsing "aussi" with nouns instead of "autant de"Ask yourself: am I comparing a QUALITY (aussi) or a QUANTITY (autant de)?
"Que" consistently means "than" or "as" in all comparison typesOmitting "que" entirely or replacing it with "de" or "comme"Remember: no "que" = no complete comparison. It's always required.
Easy to combine with preference verbs (préférer, aimer mieux)Confusing "meilleur" (adjective) with "mieux" (adverb)Meilleur describes a NOUN; mieux describes a VERB. "Un meilleur film" vs. "Il joue mieux."
KEY TAKEAWAY
Think of meilleur and mieux like two lanes on a highway. The "adjective lane" (meilleur) is for describing nouns — un meilleur résultat (a better result). The "adverb lane" (mieux) is for describing actions — elle chante mieux (she sings better). Driving in the wrong lane causes confusion!

Connection to Superlatives & Advanced Structures

Once you've mastered comparatives, the next step is the superlative — expressing that something is the MOST or LEAST of a quality. The French superlative is built directly from the comparative: you simply add a definite article (le, la, les) before plus or moins. This makes the transition very natural once you're comfortable with comparisons.

Comparative vs. Superlative: Key Differences
FeatureComparative (this lesson)Superlative (next level)
What it expressesA is MORE / LESS / AS __ AS BA is THE MOST / THE LEAST __
Structureplus/moins/aussi + adj + quele/la/les + plus/moins + adj (+ de + group)
ExampleParis est plus grand que Lyon.Paris est la plus grande ville de France.
Irregular (bon)meilleur(e) quele/la meilleur(e) de
Number comparedExactly two itemsOne item against an entire group

Beyond superlatives, you'll eventually encounter advanced comparison structures such as de plus en plus (more and more), de moins en moins (less and less), and plus… plus… (the more… the more…). These progressive comparisons add nuance and sophistication to your writing and conversation. For now, mastering plus, moins, aussi + que gives you a rock-solid foundation for all of these future structures.

Practice Problems

PROBLEM 1CONCEPTUAL
What are the three French comparison words, and what type of comparison does each express? Give the English equivalent of each.
PROBLEM 2BASIC
Translate into French: "The movie is more interesting than the book." (le film, intéressant, le livre)
PROBLEM 3INTERMEDIATE
Complete each sentence with the correct comparison word and the proper form of the adjective in parentheses. a) Ma sœur est _____ _____ (grand) _____ mon frère. (My sister is taller than my brother.) b) Ce restaurant est _____ _____ (bon) _____ l'autre. (This restaurant is better than the other one.) c) Les chats sont _____ _____ (actif) _____ les chiens. (Cats are less active than dogs.)
PROBLEM 4APPLIED
You are writing a review comparing two smartphones for a French tech blog. Write three sentences: one using plus…que, one using moins…que, and one using aussi…que. Use at least one irregular comparative. Vocabulary hint: léger (light), rapide (fast), cher (expensive), bon (good), l'écran (screen).
PROBLEM 5CRITICAL THINKING
A student writes: "Marie a aussi livres que Pierre. Le café est plus bien que le thé. Les filles sont plus intelligentes de les garçons." There are three distinct errors in these sentences. Identify each error, explain why it is wrong, and provide the corrected version.

Lesson Summary

French comparisons are built on a single, elegant formula: plus / moins / aussi + adjective or adverb + que + the second element. Use plus for superiority (more), moins for inferiority (less), and aussi for equality (as…as). When comparing quantities of nouns, switch to autant de for equality. The adjective always agrees in gender and number with the first noun, while the comparison words themselves never change.

Watch out for the key irregular comparatives: bon → meilleur (adjective, "better"), bien → mieux (adverb, "better"), and mauvais → pire ("worse"). Never say plus bon or plus bien. Mastering these comparisons opens the door to superlatives and progressive comparisons — the building blocks of expressing nuanced opinions, preferences, and evaluations in French.
