The OEDILF is an attempt to define every word in the English language – in the form of a limerick. For example:
aglycone by Chris Doyle (Limerick #5325)
When a glycoside enters the gut,
By hydrolysis it will be cut.
The aglycone’s the part
That will pass to the heart
While the sugar goes straight to the butt.
It’s quite spectacularly pointless, and therefore utterly brilliant.
