Half rhyme

Half rhyme is consonance on the final consonants of the words involved. It is widely used in Irish, Welsh, and Icelandic verse. Some examples are ill and shell and dropped and wept.

The first English poet to use half rhyme was Henry Vaughan, but it was not until it was used in the works of W. B. Yeats and Gerard Manley Hopkins that half rhyme became popular among English-language poets.
