语境与语域Context & Register

发音与拼写Pronunciation & Spelling
The first syllable of deadbolt /ˈdɛd.boʊlt/ rhymes with dead, head, and said (/dɛd/, /hɛd/, /sɛd/). The final syllable matches bolt, colt, and dolt (/boʊlt/, /koʊlt/, /doʊlt/), but because stress falls on the first syllable, those are not whole-word rhymes. Beware lookalikes: bold /boʊld/ ends with /d/ instead of /t/, and deed /diːd/ has a different vowel.
