- There are several theories on the origin of the name
of the Irish county of Co.Clare:
- When the boundaries of
the modern Co.Clare
were fixed by Sir Henry Sidney
it was apparently named after the de Clares
(it did not have a separate name before,
because it was just part of Thomond).
So ultimately Co.Clare would be after Clare in Suffolk.
- Another theory is that Co.Clare is after the Gaelic "clar",
meaning a plain, or a level piece of land.
The county's Irish name today is "An Clar".
- A further theory is that the Gaelic "clar" also means
a plank or board,
S of Ennis,
is named from
a bridge of planks built over the river Fergus,
and the county is named after that.
