Paradigm

1.2.1. -n- stem nouns (weak declension)

This type of declension includes masc, fem and neut nouns.

Only several OE nouns belonged to the -n- stemmed type. A remnant of this type of declension in Mod E is the pl ending -en in a small number of nouns, such as oxen, children, etc.

nouns, -n- stem, masculine gender

masc and fem nouns of the -n- stemmed type oft denote the doer of the action, thus being nomina agentis; e.g. déma (judge) ← deman (to judge; to deem, think); hunta (hunter) ← huntian (to hunt), etc.
