Answer:
The correct answers are:
1. imperfect rhyme: slant rhyme.
2. a pattern of rhyme for an entire poem: rhyme scheme.
3. words similar in spelling that appear to rhyme: eye rhyme.
4. words whose sounds correspond exactly: perfect rhyme.
5. corresponding sound of two or more words: rhyme.
Explanation:
1. "Imperfect rhyme" is a synonym for slant rhyme, they are the contrary of a perfect rhyme in terms of spelling and pronunciation, and they could also be called half-rhyme.
2. "A pattern of rhyme for an entire poem" is a rhyme scheme and is more common in sonnets, traditional poems, Romantic poetry, and in the ones which follow a very strict poetic pattern, although this is not a mandatory poetic device because there are a lot of free verse poems (with no rhyme scheme).
3. "Words similar in spelling that appear to rhyme" are called eye rhyme because they look like rhyming, although their pronunciation is quite different, some words would be perfect rhymes in the past, but language changes have made them only look like rhymes, which is why it is called an "eye" rhyme.
4. "Words whose sounds correspond exactly" is the most accurate definition of a perfect rhyme, they usually match in spelling and pronunciation, sometimes even look like the same words (even though with different meanings), for instance "fast" and "last".
5. "Corresponding sound of two of more words" is the perfect definition of a rhyme, that is the elementary feature of a rhyme and how it functions by words matching in spelling and/or pronunciation.
