Is smile and style a slant rhyme?

Yes, "smile" and "style" are considered a slant rhyme, also known as an imperfect rhyme or near rhyme.

Here's why:

* Similar sounds: They share the same vowel sound ("ai") but the consonant sounds before and after the vowel differ.

* Not perfect rhymes: Perfect rhymes have identical vowel and consonant sounds after the stressed syllable.

Slant rhymes often add a subtle musicality or a hint of playfulness to poetry and song lyrics.
