Pronunciation & Spelling
None of these words rhymes exactly with buttock /ˈbʌtək/, because the stressed vowel in buttock is /ʌ/ followed by /tək/. Haddock, paddock, and hammock are spelling lookalikes but have /æ/; hummock and stomach share the /ʌ/ vowel but differ in /m/ vs /t/; bullock has /ʊ/. So treat the spelling ending -ock with caution.
