Old English

Etymology

From earliest Old English *ons, from Proto-West Germanic *ansu, from Proto-Germanic *ansuz (“god, deity”), from Proto-Indo-European *h₂ems- (“engender, beget”). Cognate with Old Norse áss.

Pronunciation

IPA^(key): /oːs/

Noun

ōs m

a god
the runic character ᚩ (/o/ or /oː/)

Usage notes

The genitive plural ēsa (attested in ēsa gescot “the shot of the ēse”) and names such as Esegar display i-mutation, despite being a u-stem. This is likely a fossilization from an earlier stage between Proto-West Germanic *ansu and early Old English *ons, in which i-mutation was applied to the attested declined forms due to the word’s archaic meaning, rather than its active usage.
The nominative plural likely had the same process from above applied to it as well, in the form of *ēse.
Both i-mutated, and typically-expected forms for each affected declension are provided in the table below:

Alternative forms

Etymology

Hamp derives this from Proto-Celtic *sonts, plural *sontes (whence ot); ultimately from Proto-Indo-European *h₁sónts.^[1] Copular origin explains the use of independent subject pronouns with this conjunction, which otherwise are usually used with the copula is.

A more traditional theory, assumed by Pedersen and Thurneysen among others, supposes that this is a contraction of ocus (“and”), with the apparent copular behaviour being analogical.^[2]

Conjunction

os (third-person plural ot)

disjunctive conjunction

Usage notes

The conjunction takes on the form ot when used with the third-person plural pronoun é and os elsewhere.
