OIcel declension

OIcel ijō-stems

OIcel inherits PGmc ī~jō-stems¹ (all feminine) with the following paradigm²

case	fem.sg	fem.pl
nom	erm-r	erm-ar
gen	erm-ar	erm-a
dat	erm-i	erm-um
acc	erm-i	erm-ar

These are often grouped with the OIcel ō-stems, but deviate strongly from the normal paradigm, with retention of the nominative -r otherwise only reflected in OIcel a-stems and with ∅-endings replaced with -i.

Subclasses

A handful of stems ending in -ijo also have -j- insertion.

case	fem.sg	fem.pl
nom	gýg-r	gýg-j-ar
gen	gýg-j-ar	gýg-j-a
dat	gýg-i	gýg-j-um
acc	gýg-i	gýg-j-ar
