发音与拼写Pronunciation & Spelling
None of these words is a true rhyme with attenuated. Its stressed vowel is /ɛ/ in the second syllable, followed by /n.../. Accentuated is the closest lookalike, sharing the stressed vowel and an /n/, but it continues with /tʃ/ instead of /j/, so it does not rhyme. The other words share only the spelling ending -uated; their stressed vowels and following consonants differ. Treat them as spelling lookalikes, not sound rhymes.
