Hah TIL. So it's the river Welsh river on the English side of the Bristol channel.

I often feel like I would understand a lot more names if I bothered learning Welsh. It's pretty popular for made up climbing route names too, because Wales is so good for it I guess. Allegedly some of the classics in the Avon gorge are Welsh derived but I could never figure them out to be sure.

They're more likely Celtic words that live on in Welsh.

It’s lovely isn’t it? There’re a good few of these things around: notably Torpenhow Hill (which killjoys dispute); and ones like Pendle Hill (which they don’t).

There is also a nebulous region within England that might be called Avon, depending on the moon's phase and the price of loons.

There is a river Avon in England. Welsh at least (inst. celtae) has a noun for "river" which is "afon".

Recommend looking up the pronunciation of that there afon :)

The Welsh "afon" derives from the earlier Celtic "abona" meaning "river". Also related to the Celtic "afanc" which was some kind of aquatic monster.

Makes sense given Welsh’s evolution from Britannic. Much to my shame, I only started visiting Wales in later life, and there’s really something in the language that grabs me quite deeply. Once I’ve got my Polish down to pat, I tell myself.

You avon a chwerthin?
