发音与拼写Pronunciation & Spelling
Words that share the -ator ending often have the same final /eɪtɚ/ sound. 'Traitor' provides an exact rhyme with the same stressed vowel and ending. 'Creator' and 'narrator' also match the final part, though their stress patterns differ. Words like 'actor' (ˈæktɚ) and 'doctor' (ˈdɑktɚ) look similar in spelling but have different vowel sounds (short æ and ɑ), so they are not rhymes.
