发音与拼写Pronunciation & Spelling
No common English word rhymes with diatom (/ˈdaɪətəm/). Atom (/ˈætəm/) and autumn (/ˈɔːtəm/) share only the final syllable /-təm/, not the stressed vowel. Diagram (/ˈdaɪəɡræm/), dialect (/ˈdaɪəlekt/), and dial (/ˈdaɪəl/) match the initial /ˈdaɪə/ sound and spelling dia but are not rhymes. Diet (/ˈdaɪət/) is a close partial sound match to diatom's first two syllables.
