Ogma is found in Cath Mag Tuired wirth the
following variations:
Ogmai, Ogmae, Ogme and, with the vocative
singular, Ogmau (which looks to be a scribal error).
The -a- of Ogma is due to a late trend in Old Irish
to write -a- for -ae- (in some late sources, the -m- of Ogma is lenited and
spelled Ogmha).
The name should have the following
declension:
Masculine
-io- tem
Sing. Common Celtic
N Ogm(a)e
(*Ogmios)
V Ogm(a)i
(*Ogmie)
A Ogm(a)e
