发音与拼写Pronunciation & Spelling
Only 'coincident' comes close to rhyming: in /koʊˈɪnsɪdənt/ it shares the stressed /ɪn/ and the final /s(ɪ)dənt/ with the target, though the unstressed vowel may vary. 'Accident' looks similar but starts with /æk/, and 'president', 'resident', 'evident', and 'confident' all have different stressed vowels, so they do not rhyme with 'incident'; they are listed for the shared '-dent' spelling.
