There are three well-known unrhymable words in the English language. Curiously, all are colour-related. The words are: purple, orange, silver. Here we attempt to demonstrate that such rhyming is possible.
Purple: The following illustrative little ditty is offered:
Orange: We simply observe that, in Yorkshire, orange rhymes naturally with doorhinge. Southerners are invited to repent of their myopic, regionalist presuppositions!
Silver: This one is more of a challenge. Here is a rather contrived, quack-Shakespearean idea, with a layout to demonstrate its working.
In a real poem the layout would probably use longer lines; in this example our 'silver' rhyme is demoted to being internal.
Other suggestions are hereby solicited.
Michael Sadgrove, recently retired Dean of Durham (and the inspiration behind this little poem) has brought four more words to my attention for which there appear to be no true rhymes: wasp, tungsten, peckish, parquet.
Suggestions are hereby solicited.
