2. imperative of ose

• “os” in The Nynorsk Dictionary.
• “os”, in Norsk Ordbok: ordbok over det norske folkemålet og det nynorske skriftmålet, Oslo: Samlaget, 1950-2016

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.

• IPA^(key): /oːs/

ōs m

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

• 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.

• Middle French: os
  • French: os

• as, es, is (aberrant Würzburg forms)

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]

os (third-person plural ot)

1. disjunctive conjunction

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