Which term describes a phonetic variant of a phoneme that does not change meaning and is conditioned by position in a word?

• A. Allophone
• B. Phone
• C. Idiom
• D. Parataxis

Answer: (A)

This is about how a single phoneme can have different sound realizations depending on context, without changing the word’s meaning. Those context-dependent realizations are called allophones. The phoneme is the abstract unit that can distinguish meaning, while its allophones are the actual pronunciations you hear in different positions or environments in speech. Because these variants occur in specific contexts, they don’t create new words or meanings by themselves.

For example, the sound of /p/ in English has two common allophones: [pʰ] as in pit (aspirated at the start of a stressed syllable) and [p] as in spin (unaspirated after an s-cluster). Both sounds are realizations of the same /p/ phoneme, and swapping them in the right contexts wouldn’t change the word’s meaning. Another familiar case is the American English /t/ that can be a quick, flapped [ɾ] between vowels when the second vowel is unstressed; this is again an allophonic variant of the same phoneme.

A phone is any distinct speech sound, not tied to a phoneme’s identity. An idiom is a fixed expression whose meaning isn’t predictable from its parts, and parataxis is a syntactic arrangement of clauses.
