Pronunciation

Forms

sunu m (nominative plural suna) (strong u-stem)[1]

Etymology

It is inherited from Proto-West Germanic *sunu, from Proto-Germanic *sunuz (“son”).[1][2] The Proto-Germanic noun is found in all the old Germanic languages: Gothic 𐍃𐌿𐌽𐌿𐍃 (sunus), Old Norse sonr, Old Frisian sunu, Old Saxon sunu and Old High German sunu.[2][3][4]

It continues Proto-Indo-European *suHnús (“son”),[2][1] which also gave Sanskrit सूनु (sūnú), Lithuanian sūnus and Proto-Slavic *synъ.[3][1] Orel explains the short vowel of Germanic, against the long one of these forms, by a shortening before the accent.[3] Holthausen and Köbler derive the noun from the root Proto-Indo-European *sewH- (“to give birth”) and compare Old Irish suth (“birth, fruit”).[5][4]

It is a u-stem noun, with the ending -a in the genitive and dative singular and in the plural.[6]

Earliest recorded meaning

The word is first recorded in the Corpus Glossary, of the early ninth century, where faedran sunu “father's brother's son” glosses Latin “patruelis”, a cousin.[7][8] The Vespasian Psalter gloss of the mid-ninth century has sunu min ðu earð “you are my son” for the Latin “filius meus es tu” of Psalm 2.[9][8]

Semantic evolution

Its sense is “son”, also more widely “descendant”, and the young of animals.[10][4] In religious texts it is the Son of God, Christ.[10][11] With the genitive of the father's name it forms a by-name, Oddan sunu “Odda's son”,[11] and in Beowulf it is mostly used so, as in sunu Healfdenes.[12] Bosworth and Toller also record weak forms such as suna and sunan.[13] Compounds name other kinsmen: brōþorsunu and sweostorsunu “nephew”, dohtorsunu “grandson”.[14][15][16]

The word continued as Middle English sone,[17] now English son.[18]
