Pararhyme is a kind of near rhyme in which two words share the same consonant sounds in the same order, but their vowels differ. The effect is a muted, unsettled sound rather than a full rhyme, and poets often use it to create tension or unease. It is sometimes called double consonance.
This term was coined by Edmund Blunden to describe a form of 'near rhyme' where the consonants in two different words are exactly the same but the vowels vary. Pararhyme is particularly a feature of the poetry of Wilfred Owen. For example, in Owen's unfinished poem Strange Meeting we find lines ending with words such as 'groaned' and 'groined' and 'hall' and 'Hell'. Pararhyme is more commonly known as double consonance.
Example
The wind came thin across the moor
and sent my thoughts to distant shore;
my hopes were held in stone and steel,
but time would bend what I could not feel.
