发音与拼写Pronunciation & Spelling
The pattern is the spelling ending -ous. Famous, nervous, dangerous and enormous are true matches for the final unstressed /əs/ of nitrous. Various and curious also contain -ous but add a /i/ glide, so they are only spelling matches. Be careful with citrous /ˈsɪtrəs/: it looks similar but has a different stressed vowel, so it does not rhyme.
