发音与拼写Pronunciation & Spelling
Perfidious, fastidious, and hideous rhyme with insidious (/ɪnˈsɪdiəs/) — they all have the stressed vowel /ɪ/ followed by /diəs/. Tedious looks similar in spelling but uses a long /iː/ (/ˈtiːdiəs/), so it does not rhyme. Note that hideous rhymes despite its different spelling (-deous).
