A decision before an answer
- The smallest unit of sound and the smallest unit of meaning are different things, and exam questions live in the gap.
- Your goal: Order the units of language from phoneme to sentence.
Order the units
- Language is hierarchical. Phonemes are the smallest sound units that distinguish meaning (/b/ versus /p/); morphemes are the smallest meaning-bearing units (un-happy-ness has three).
- Syntax governs how words combine into phrases and sentences; semantics concerns meaning. A sentence can be grammatical yet meaningless — syntax and semantics are separable.
The word unhappiness contains how many morphemes?
Un + happy + ness: three meaning-bearing units; letters are not morphemes.
Hear the categories
- Speech perception is categorical: continuous acoustic variation is heard as discrete phonemes, so a sound between /b/ and /p/ is reported as one or the other.
- Listeners segment a continuous stream using transitional probabilities and knowledge, not audible gaps between words.
A sound acoustically intermediate between /b/ and /p/ is reported as clearly one or the other. This illustrates:
Continuous acoustic input is perceived as discrete phoneme categories.
Read by routes
- Reading links print to sound and meaning. Skilled readers use both a grapheme-to-sound route (sounding out) and a direct whole-word route for familiar words; dyslexia research separates phonological decoding deficits from surface patterns.
- Eye-movement studies show reading is a series of fixations and saccades, not smooth gliding.
Un-happy-ness is three morphemes but the spoken form has more phonemes than syllables. A sound midway between /b/ and /p/ is heard as clearly one or the other — categorical perception. Colourless green ideas sleep furiously is grammatical but meaningless, separating syntax from semantics.
The smallest sound units that distinguish meaning in a language are called ____.
Phonemes distinguish meaning; morphemes are the smallest units that carry meaning.
Weigh the bilingual evidence
- Bilingualism research separates language proficiency from general intelligence: balanced bilinguals show executive-control practice effects, while subtractive schooling can harm both languages.
- Second-language learning declines with age of onset, especially for pronunciation and grammar, without a single sharp critical cut-off.
Counting morphemes by letters or syllables, or treating word boundaries in speech as physically present; segmentation is inferred by the listener.
Which answer fits this case?
Order the units of language from phoneme to sentence
A grammatically correct sentence must be meaningful.
Syntax and semantics are separable; grammatical nonsense is possible.
Keep the distinctions
- morpheme 语素 — The smallest meaning-bearing unit of language.
- syntax 句法 — The rules governing how words combine into phrases and sentences.
- Order the units of language from phoneme to sentence.
- Explain speech perception and reading processes.
- Compare bilingual and second-language evidence.
