What is the term for words that sound similar but do not rhyme exactly?

The term for words that sound similar but do not rhyme exactly is near rhyme, also known as slant rhyme, half rhyme, or imperfect rhyme.

These words share some phonetic similarities, often in their vowel sounds or consonant endings, but don't have the same ending sound.

Examples:

* "love" and "move" - share the vowel sound but end differently

* "cat" and "cot" - share the consonant sound but have different vowel sounds

* "street" and "sweet" - share the vowel sound but have different consonant sounds

Near rhymes are often used in poetry and songwriting to create a subtle sense of dissonance or to emphasize a particular word or phrase.
