发音与拼写Pronunciation & Spelling
These words all share the '-th' spelling ending with 'fifth', but none are perfect rhymes because their stressed vowel sounds differ from the /ɪ/ in 'fifth'. For example, 'sixth' has /ɪ/ but the following consonants /ksθ/ differ from /fθ/, so they do not match exactly.
