Which term describes small sound contrasts that can change meaning within a language, such as between p and b in English?

• A. Phonemic
• B. Procedural knowledge
• C. Obligatory contexts
• D. Negotiation of form

Answer: (A)

The key idea is phonemic contrasts: sounds that can change meaning in a language. In English, the sounds /p/ and /b/ differ in voicing, so they belong to separate phonemes. This is demonstrated by minimal pairs like “pat” and “bat,” where swapping the initial sound changes the word's meaning. Phonemes are the abstract units that carry meaning; the actual spoken sounds (phonetics) are different surface realizations of those units, but what matters for meaning is the contrast between them. The other terms don’t describe how sound differences create meaning, so they don’t fit as well.
