发音与拼写Pronunciation & Spelling
Only 'perceptibly' rhymes exactly: both it and the target have the stressed sequence /sɛptɪbli/. The other five share the spelling suffix '-ibly' but not the rhyme: 'incredibly' has /krɛdɪbli/ (the coda /d/ differs from /pt/), while 'visibly', 'audibly', 'legibly', and 'possibly' all use the weak vowel /ə/ in the suffix, giving /-əbli/ rather than /-ɪbli/.
