A Note on Proest.
What is proest?
Proest is a technique used in Welsh poetry. It’s a kind of half-rhyme in which the end consonant is the same, but the vowel is different though of a similar length, for example the English word ‘cap’ makes a proest with the Cymraeg (Welsh) word twp ( meaning ‘stupid’). I take this example from Mererid Hopwood’s Singing in Chains: Listening to Welsh Verse, in which there is a longer explanation of proest.
(See: Mererid Hopwood, Singing in Chains: Listening to Welsh Verse (Llandysul, Carmarthenshire: Gomer, 2004), 67).
