The word limerick is a rather peculiar noun
It was named after Luimneach, a small Irish town
Because there was a song verse that included its name
Often found in these poems, which brought it some fame.
So let's break it down:
Luimneach comes from lom na each, which was found
to have a definition of "grassless horse ground".
That developed from Proto-Celtic for over an eon
And had the same meanings in Proto-Indo-European
But more with a lomm es hekwos sound.
Limericks today are usually one verse
And normally funny, but they're kept terse
They follow a predictable array
A rhyme pattern of a/a/b/b/a.
Anyway, cool origin to disperse.
Adam Aleksic, a freshman studying linguistics at Harvard University, has been described as the internet's sixth most famous etymologist. He has disturbing interests in words, vexillology, geography, board games, limericks, and law, and he loves writing about himself in the third person.
