发音与拼写Pronunciation & Spelling
Lipid has two pronunciations: /ˈlɪpɪd/ and /ˈlaɪpɪd/. None of these words is a perfect rhyme: rapid, vapid, tepid, stupid, and intrepid only share the -pid spelling, and their stressed vowels differ (/ˈræpɪd/, /ˈvæpɪd/, /ˈtepɪd/, /ˈstjuːpɪd/, /ɪnˈtrepɪd/). Liquid /ˈlɪkwɪd/ is a lookalike with /kw/ instead of /p/.
