What is the term for the smallest unit of sound that affects the meaning of speech?

• A. Phoneme
• B. Morpheme
• C. Syllable
• D. Grapheme

Answer: (A)

The smallest unit of sound that can change meaning is a phoneme. Phonemes are the distinct sounds in a language that can differentiate words; for example, the sounds /p/ and /b/ distinguish "pat" from "bat." If you swap one phoneme for another, you typically change the word’s meaning, which is why phonemes are considered the smallest meaningful sounds in speech. Morphemes are the smallest units of meaning themselves (like the plural -s in "dogs"), not just sounds. Syllables are chunks of a word around a vowel that help with pronunciation and rhythm, but they aren’t defined by meaning. Graphemes are written symbols representing sounds or letters, which relates to writing rather than the actual sound distinctions in spoken language.
