By the way. There are a variety of rhymes.

The one we normally think of are "sound-alikes", and the words look alike as well. In Gaelic poetry, one of the most common schemes is "vowel" sound similarities. This type of rhyme doesn't normally appear from line to line at the end.

It uses alliteration of vowels within the words. The words could be quite different except for the vowel within the word. It also doesn't have to end words the same. Words that have the same sound vowel are picked, and the rhyme could be at the end of the line, end of one line and start of the next, or even from top to bottom all in the middle of the line.

Lots of choices. And that's way before getting to the rhyme of alliteration.
