System of Declensions

Though the stem-suffixes merged with the root, declensions were still existent in OE and were based on the former IE stem-suffixes:

a-stem – the most numerous declension (M, N):

Case	Masculine	Neuter
Singular	Plural	Singular	Plural
Nom, Acc	fisc	fiscas	dēor	dēor!
Gen	fisces	fisca	dēores	dēora
Dat	fisce	fiscum	dēore	dēorum

Traces of a-stem in Modern English:

· -es (M, Sg, Gen) à ‘s (student’s book) – Possessive Case;

· -as (M, Pl, Nom) à -(e)s (watches, books) – plural ending for the majority of nouns;

· -  (N, Pl, Nom) à zero ending (deer, sheep) – homogeneous Sg and Pl.

n-stem (M, N, F):

Case	Masculine
Singular	Plural
Nom	nama	naman
Gen	naman	namena
Dat	naman	namum
Acc	naman	naman

Traces of n-stem in Modern English:

· -an (M, Pl, Nom) à -en (oxen, children, brethren) – irregular plural ending.

root-stem – never had stem-suffix, words consisted of just a root(M, F):

Case	Masculine
Singular	Plural
Nom, Acc	fōt	fēt
Gen	fotes	fōta
Dat	fēt	fōtum

Traces of n-stem in Modern English:

· root-sound interchange (M, Pl, Nom) à root-sound interchange (men, geese, mice) – irregular Plural.
