Eye rhyme is when two words look like they should rhyme because they are spelled the same. However, the words do not actually rhyme because they are not pronounced the same. Thrush and bush both have the same ush spelling at the end. Thrush is pronounced with a short u /uh/ sound. Whereas bush has a short /oo/ sound.
Bough and Plough both have the "ow" sound. Shrill and hill both have the short /i/ sound. Shed and bred both have the short /e/ sound.
