cod · could
cod /kɒd/ vs could /kʊd/ — short /ɒ/ (jaw wide open) vs short /ʊ/ (lips lightly rounded). The L in could is silent.
Two back vowels — one open, one rounded. cod uses short /ɒ/ — jaw wide open. could uses short /ʊ/ — lips lightly rounded, mouth almost closed. And the L in could is completely silent!
💡 Silent L alert: could is pronounced /kʊd/ — the L is NOT said.
The same applies to would /wʊd/ and should /ʃʊd/ — all three have silent L.
