Pronunciation & Spelling
Words like 'junction', 'conjunction', 'dysfunction', 'injunction' share the same stressed vowel /ʌ/ and ending /ŋkʃən/, thus rhyme with 'function'. Words like 'action' and 'fraction' have the same '-ction' spelling but differ in vowel sound (/æ/ vs /ʌ/), so they do not rhyme.
