发音与拼写Pronunciation & Spelling
These words all rhyme with the final stressed /aɪd/ of cyanide. The first part of cyanide is /saɪə/, so do not confuse it with sign /saɪn/ or cyan /ˈsaɪæn/. Chemical -ide words like chloride and fluoride share the -ide spelling and final /aɪd/ sound, but they usually do not stress that syllable, so they are not perfect rhymes.
