What do you call "rhymes" which are spelt but not sounded the same way?
Solution 1:
They are called eye rhymes. Here is a reference from Brittanica:
Eye rhyme, in poetry, an imperfect rhyme in which two words are spelled similarly but pronounced differently (such as move and love, bough and though, come and home, and laughter and daughter). Some of these (such as flood and brood) are referred to as historical rhymes because at one time they probably had the same pronunciation.
