Constructing Phoneme InventoriesQuestion 1 of 10

In analyzing a language's sibilant system, a linguist finds [s], [ʃ], and [ɕ] in the following environments: [s] before [a, o, u], [ʃ] before [i, e] and word-finally, [ɕ] only before [i] in morphologically complex words. Native speaker perception tests show that speakers consistently identify [s] and [ʃ] as different sounds but group [ɕ] with [ʃ] unless explicitly trained to distinguish them. What phonemic analysis best accounts for this evidence?

Three phonemes /s/, /ʃ/, and /ɕ/ because all three sounds have distinct articulatory and acoustic properties
Two phonemes /s/ and /ʃ/, with [ɕ] as an allophone of /ʃ/ in morphologically derived environments
Two phonemes /s/ and /ʃ/, with [ɕ] as a morphophonological variant requiring separate treatment from core phonology
One phoneme /s/ with [ʃ] and [ɕ] as environmentally conditioned allophones showing varying degrees of palatalization

Question 1

In analyzing a language's sibilant system, a linguist finds [s], [ʃ], and [ɕ] in the following environments: [s] before [a, o, u], [ʃ] before [i, e] and word-finally, [ɕ] only before [i] in morphologically complex words. Native speaker perception tests show that speakers consistently identify [s] and [ʃ] as different sounds but group [ɕ] with [ʃ] unless explicitly trained to distinguish them. What phonemic analysis best accounts for this evidence?

  1. Three phonemes /s/, /ʃ/, and /ɕ/ because all three sounds have distinct articulatory and acoustic properties
  2. Two phonemes /s/ and /ʃ/, with [ɕ] as an allophone of /ʃ/ in morphologically derived environments (correct answer)
  3. Two phonemes /s/ and /ʃ/, with [ɕ] as a morphophonological variant requiring separate treatment from core phonology
  4. One phoneme /s/ with [ʃ] and [ɕ] as environmentally conditioned allophones showing varying degrees of palatalization
Explanation: The correct answer is B. The perceptual grouping of [ɕ] with [ʃ] by naive speakers, combined with [ɕ]'s restriction to morphologically complex environments, suggests it's an allophone of /ʃ/ rather than a separate phoneme. The clear perceptual distinction between [s] and [ʃ] supports their phonemic status. Choice A ignores the perceptual evidence and morphological conditioning. Choice C unnecessarily complicates the analysis by invoking morphophonology. Choice D incorrectly groups perceptually distinct sounds [s] and [ʃ] as allophones.

Question 2

During phonemic analysis of a language isolate, a researcher identifies sounds [x], [χ], and [h] with the following properties: [x] occurs after front vowels, [χ] occurs after back vowels, [h] occurs word-initially and after central vowels. Acoustic measurements show [h] has significantly different spectral properties from [x] and [χ]. Substitution tests reveal that replacing [x] with [χ] in back vowel contexts sounds 'foreign' but comprehensible, while using [h] in post-vocalic position renders words unintelligible. How should these sounds be classified?

  1. Two phonemes: /x/ with allophones [x] and [χ] conditioned by vowel backness, and /h/ as a separate phoneme (correct answer)
  2. Three separate phonemes because each sound has measurably different acoustic properties and distinct distributional patterns
  3. Two phonemes: /χ/ as the basic form with [x] as a fronted allophone, and /h/ as a separate phoneme
  4. One phoneme /h/ with [x] and [χ] as strengthened allophones in post-vocalic environments
Explanation: When analyzing sounds in phonemic analysis, you need to apply three key tests: complementary distribution, acoustic similarity, and functional substitution. These determine whether sounds are separate phonemes or allophones of the same phoneme. Looking at the evidence systematically: [x] and [χ] show complementary distribution (never occur in the same environment) and are acoustically similar enough that substitution causes only "foreign" pronunciation rather than unintelligibility. This classic allophonic relationship indicates they're variants of one phoneme, with the distribution pattern ([x] after front vowels, [χ] after back vowels) suggesting /x/ as the underlying form with vowel-conditioned allophony. Meanwhile, [h] has distinct acoustic properties and causes unintelligibility when substituted, indicating it's a separate phoneme entirely. Choice A correctly identifies this two-phoneme analysis with /x/ having allophones [x] and [χ]. Choice B incorrectly treats acoustic differences as definitive - allophones can have measurable acoustic differences while remaining variants of one phoneme. Choice C arbitrarily selects /χ/ as basic rather than following the more common pattern of using the first-mentioned or more frequent variant. Choice D completely misses the allophonic relationship between [x] and [χ], incorrectly grouping all three sounds under /h/ despite clear evidence that [h] patterns differently. Remember: complementary distribution plus acoustic similarity typically indicates allophony, while functional substitution tests reveal phonemic boundaries. Don't let measurable acoustic differences fool you into assuming separate phonemes when distribution patterns suggest allophonic variation.

Question 3

A linguist analyzing a language discovers the following sound patterns: [p] occurs only before [a] and [o], [b] occurs only before [i] and [u], and [β] occurs only between vowels. Native speakers consistently fail to distinguish [p] from [β] in perception tests, but easily distinguish [b] from both [p] and [β]. When constructing the consonant phoneme inventory, how should these three sounds be classified?

  1. [p], [b], and [β] are three separate phonemes because they have different distributions
  2. [p] and [β] are allophones of one phoneme, while [b] is a separate phoneme (correct answer)
  3. [p] and [b] are allophones of one phoneme, while [β] is a separate phoneme
  4. All three sounds are allophones of a single phoneme because they share similar articulatory features
Explanation: The correct answer is B. Since [p] and [β] are in complementary distribution (never occur in the same environment) and native speakers cannot perceptually distinguish them, they are allophones of the same phoneme. [b] is a separate phoneme because it contrasts with the [p]/[β] phoneme and speakers can distinguish it. Choice A incorrectly assumes distribution alone determines phonemic status. Choice C ignores the perceptual evidence and complementary distribution of [p] and [β]. Choice D incorrectly groups all sounds together despite clear phonemic contrasts.

Question 4

While analyzing a language's vowel system, a linguist discovers that [e] and [ɛ] show the following distribution: [e] appears in closed syllables ending in nasals, [ɛ] appears in all other environments. However, loanwords from the dominant contact language consistently maintain [e] in non-nasal environments, and younger speakers increasingly use [e] where older speakers use [ɛ]. Given this sociolinguistic variation, how should the vowel inventory be constructed?

  1. Two phonemes /e/ and /ɛ/ because loanword evidence demonstrates that speakers can maintain phonemic contrasts in all environments
  2. One phoneme /ɛ/ with [e] as an allophone, treating loanwords as foreign phonology outside the core system
  3. One phoneme /e/ with [ɛ] as an allophone, since the historical direction of change suggests /e/ is becoming dominant
  4. Two phonemes /e/ and /ɛ/ in the innovative system, one phoneme /ɛ/ in the conservative system, requiring separate inventories for different speaker groups (correct answer)
Explanation: The correct answer is D. The sociolinguistic evidence shows a system in transition where different speaker groups have different phonological competencies. Older speakers show allophonic distribution while younger speakers show phonemic contrast, requiring recognition of both systems. Choice A incorrectly applies loanword evidence uniformly across all speakers. Choice B dismisses significant systematic variation in the speech community. Choice C oversimplifies by choosing one analysis without accounting for the documented variation across speaker groups.

Question 5

In documenting a polysynthetic language, a researcher finds that consonant clusters [mb], [nd], [ŋg] occur morpheme-internally and across morpheme boundaries, while [mp], [nt], [ŋk] occur only across morpheme boundaries where the second morpheme begins with a voiceless stop. Within single morphemes, attempted elicitation of [mp], [nt], [ŋk] consistently yields [mb], [nd], [ŋg]. Spectrographic analysis shows identical acoustic properties for [mb] regardless of morphological context. How should the nasal-stop sequences be analyzed in the consonant inventory?

  1. Six distinct consonant clusters representing separate phonemic combinations that happen to show morphological conditioning
  2. Three phonemic clusters /mb/, /nd/, /ŋg/ with /mp/, /nt/, /ŋk/ as morphophonological variants appearing at morpheme boundaries
  3. Three underlying clusters /mp/, /nt/, /ŋk/ with voicing assimilation rules creating [mb], [nd], [ŋg] in morpheme-internal contexts
  4. Six clusters analyzed as sequences of separate nasal and stop phonemes, with voicing agreement rules operating within morphological domains (correct answer)
Explanation: The correct answer is D. The acoustic identity of [mb] across contexts and the systematic voicing alternation suggest these are sequences of independent nasal and stop phonemes with morphologically-conditioned voicing agreement, rather than unitary cluster phonemes. This analysis captures the systematic nature while maintaining phonemic economy. Choice A misses the systematic voicing relationship. Choice B incorrectly treats clusters as unitary phonemes. Choice C assumes underlying voiceless clusters without justification from the morpheme-internal impossibility of [mp], [nt], [ŋk].

Question 6

A language exhibits the following consonantal alternations in morphologically related forms: [kata] ~ [kaða], [tupa] ~ [tuβa], [saki] ~ [saɣi]. Additionally, the stops [t], [p], [k] never appear intervocalically in monomorphemic words, while [ð], [β], [ɣ] never appear word-initially or after consonants. When determining the underlying phoneme inventory, what analysis best captures the systematic nature of these patterns?

  1. Six underlying phonemes (/t/, /p/, /k/, /ð/, /β/, /ɣ/) with morphologically conditioned allomorphy explaining the alternations
  2. Three underlying phonemes (/t/, /p/, /k/) with intervocalic lenition rules deriving the fricative allophones in specific environments (correct answer)
  3. Three underlying phonemes (/ð/, /β/, /ɣ/) with fortition rules strengthening fricatives to stops in morphologically derived environments
  4. Six underlying phonemes with free variation between stops and fricatives, constrained only by positional phonotactic restrictions
Explanation: The correct answer is B. The complementary distribution (stops in strong positions, fricatives intervocalically) combined with morphological alternations suggests underlying stops that weaken to fricatives in intervocalic position. This captures the systematic nature with the minimal underlying inventory. Choice A misses the predictable distribution pattern and unnecessarily doubles the inventory. Choice C incorrectly assumes fricatives as underlying despite their restricted distribution. Choice D incorrectly invokes free variation when the distribution is clearly rule-governed and predictable.

Question 7

A field linguist working with an agglutinative language observes that vowel sequences like [ai], [au], [oi] behave as single prosodic units (taking one stress, one tone), occur in positions where only single vowels otherwise appear, and resist syllable boundary insertion. However, the same vowel sequences in compound words clearly span syllable boundaries and take separate stress patterns. When constructing the vowel phoneme inventory, how should these sequences be analyzed?

  1. The sequences [ai], [au], [oi] should be analyzed as vowel phonemes distinct from their component vowels in all environments
  2. All vowel sequences should be analyzed as clusters of separate vowel phonemes to maintain consistency across morphological environments
  3. The sequences represent diphthong phonemes in monomorphemic words but vowel clusters in compounds, requiring context-sensitive analysis (correct answer)
  4. The sequences are allophones of long vowels that undergo quality changes in different prosodic environments
Explanation: When analyzing vowel sequences in field linguistics, you need to consider both phonetic behavior and morphological context. The key insight here is that identical sound sequences can have different phonological statuses depending on their structural environment. The correct approach is C because the evidence clearly shows two distinct patterns. In monomorphemic words, [ai], [au], and [oi] exhibit classic diphthong behavior: they function as single prosodic units (taking unified stress and tone), appear in positions restricted to single vowels, and resist syllable division. These are hallmarks of phonemic diphthongs. However, in compounds, the same sequences span syllable boundaries and take separate stress patterns, indicating they're clusters of distinct vowel phonemes brought together by morphological concatenation. A is wrong because it ignores the morphological conditioning—treating all instances as single phonemes would miss the systematic differences between monomorphemic and compound environments. B fails because it forces artificial consistency where the language shows clear structural distinctions. Analyzing all sequences as clusters would ignore the prosodic unity observed in monomorphemic words. D misinterprets the data entirely—these aren't length variations but qualitatively different vowel combinations, and the alternation is morphologically, not prosodically, conditioned. Study tip: In phonological analysis, always consider morphological structure. The same surface sounds can have different underlying representations depending on whether they occur within single morphemes or across morpheme boundaries. Context-sensitive analysis often reveals the most accurate picture of a language's sound system.

Question 8

A phonological analysis reveals that a language has the vowels [i, ɪ, e, ɛ, æ, a, ɑ, ɔ, o, ʊ, u] in stressed syllables, but only [i, e, a, o, u] in unstressed syllables. Minimal pairs exist for all vowel contrasts in stressed position. In unstressed syllables, [ɪ] words from careful speech correspond to [i], [ɛ] corresponds to [e], [æ] and [ɑ] both correspond to [a], and [ɔ] and [ʊ] correspond to [o] and [u] respectively. What vowel inventory best represents this system?

  1. Eleven vowel phonemes with neutralization rules reducing contrasts in unstressed syllables (correct answer)
  2. Five vowel phonemes with allophonic variants that appear only in stressed syllables due to enhanced articulation
  3. Eleven vowel phonemes in stressed syllables and five vowel phonemes in unstressed syllables, requiring position-specific inventories
  4. Five vowel phonemes with stress-conditioned enhancement rules creating additional surface contrasts in prominent positions
Explanation: The correct answer is A. The existence of minimal pairs in stressed syllables establishes eleven distinct phonemes. The systematic reduction in unstressed syllables represents neutralization of underlying contrasts rather than absence of those phonemes. Choice B incorrectly treats the stressed variants as mere allophones despite their contrastive function. Choice C unnecessarily duplicates the analysis when neutralization rules can account for the pattern. Choice D reverses the relationship by treating the reduced system as basic.

Question 9

In constructing a vowel inventory for a newly documented language, a researcher finds five vowel sounds that occur in identical phonetic environments. Acoustic analysis reveals the following F1/F2 formant patterns: Sound A [300Hz/2100Hz], Sound B [400Hz/1800Hz], Sound C [700Hz/1200Hz], Sound D [400Hz/1700Hz], Sound E [600Hz/1300Hz]. Minimal pairs exist for all possible sound combinations except B-D, where no contrasting word pairs can be found despite extensive elicitation. What is the most appropriate phonemic analysis?

  1. Five phonemes, because acoustic differences always indicate separate phonemes regardless of distributional evidence
  2. Four phonemes, with sounds B and D as allophones, because minimal pairs are the only valid test for phonemic contrast
  3. Four phonemes, with sounds B and D as contextual variants, since they lack contrastive evidence despite acoustic differences (correct answer)
  4. Three phonemes, grouping acoustically similar sounds into natural classes based on formant proximity in vowel space
Explanation: The correct answer is C. The absence of minimal pairs between B and D, despite their occurrence in identical environments, suggests they do not contrast phonemically and should be analyzed as allophones of one phoneme. The other sounds show clear contrastive evidence. Choice A incorrectly prioritizes acoustic data over functional contrasts. Choice B correctly identifies the four-phoneme analysis but gives an incomplete rationale. Choice D arbitrarily reduces the inventory without justification from the contrastive evidence presented.

Question 10

A researcher documenting an endangered language finds these consonant clusters word-initially: [pr], [tr], [kr], [pl], [kl], but notes that [tl] never occurs, despite [t] and [l] appearing frequently in other positions. Speakers reject *[tl] combinations when presented with nonce words. Additionally, historical cognates suggest that Proto-language *tl became [kl] in this language. When constructing the phoneme inventory, how should this gap be analyzed?

  1. The gap is accidental and should not affect the phoneme inventory since /t/ and /l/ exist as separate phonemes
  2. The gap represents a systematic phonotactic constraint that confirms /t/ and /l/ as distinct phonemes with restricted distribution (correct answer)
  3. The gap indicates that [t] and [l] are allophones of the same phoneme in cluster environments
  4. The gap suggests an incomplete consonant inventory requiring further fieldwork to establish the full phonemic system
Explanation: The correct answer is B. The systematic exclusion of [tl] clusters, speaker intuitions about ill-formedness, and historical evidence all point to a genuine phonotactic constraint rather than accidental gap. This confirms that /t/ and /l/ are distinct phonemes whose distribution is constrained by language-specific rules. Choice A misses the systematic nature of the constraint. Choice C incorrectly interprets phonotactic restrictions as evidence for allophonic status. Choice D unnecessarily questions the adequacy of clear evidence from multiple sources.
