Minimal pair · General American

English /æ/ vs /ʌ/Cap or cup?

Compare the stressed vowel /æ/ with /ʌ/ in short words. Each reference pair keeps its first and last consonants; X uses a different word frame with the same target vowel category. Broader vowel-training evidence motivates coverage; this binary pool remains an editorial extrapolation.

WHAT TO LISTEN FOR

A small change.
A different word.

Cat/cut, cap/cup and lack/luck contrast /æ/ with /ʌ/. Each pair shares its first consonant and its final consonant, so the vowel is the changing target.

Listen for the target sound in each word.

A common trap

A written a or u is not a dependable sound rule across all English words. These examples use stressed vowels in General American citation forms, not reduced vowels in connected speech.
