Pronunciation & Spelling
Words like spontaneous, simultaneous, instantaneous, contemporaneous, miscellaneous, and extemporaneous share the stressed /eɪ/ and following /niəs/ with extraneous, so they rhyme. Beware lookalikes beginning with extra- such as extra /ˈɛkstrə/, extraterrestrial /ˌɛkstrətəˈrɛstriəl/, and extraordinary /ɪkˈstrɔːrdəneri/, which have a different /ɛkstrə/ or /ɪkˈstrɔːr/ sound and do not rhyme.
