The words which differ only in one phoneme ➡ These are called minimal pairs. ➡ Minimal pairs are pairs of words where a single sound (phoneme) difference changes the meaning. ➡ Example:
bat /bæt/ vs pat /pæt/ → differ only in the initial phoneme /b/ vs /p/
ship /ʃɪp/ vs sheep /ʃiːp/ → differ only in the vowel phoneme /ɪ/ vs /iː/
