Identify the odd pair out based on rhyme pattern:

Look at the vowel sounds. Mood and brood rhyme (/uːd/). Stake and lake rhyme (/eɪk/). Door and floor rhyme (/ɔː/).

“Have” is said /hæv/, with a short vowel. “Grave” is said /ɡreɪv/, with a long “ay” sound. They look alike in spelling but do not sound alike, so they do not rhyme. Have and grave is the odd pair out.
