Internal rhyme is rhyme that occurs within a line of poetry, or between words inside nearby lines, rather than only at the line endings. It often links a line's middle and ending sounds, or two sounds within the same line, helping create musicality, momentum, or emphasis.
Poets use internal rhyme to make a poem feel more fluid and to draw attention to particular words or phrases.
Example
The moon lit the road with a silver glow,
I wandered slower where the cold winds blow.
Here, glow and blow create internal rhyme within the poem's lines.
