Forms

υἱός (huiós) m (genitive υἱέος or υἱοῦ); second declension[1] Mycenaean Greek i-jo, probably also i-ju, dative i-je-we and i-we.[2] Early Attic and other early inscriptions inflect it as a u-stem, nominative υἱύς (huiús) (also ὑύς, ὕς), genitive υἱέος; the o-stem forms appear in Attic inscriptions only after 350 BC.[3] Homer also has the forms υἱέος, υἷος, υἷα and the plural υἷες.[4][5]

Etymology

It is a second-declension remodelling of the older υἱύς (huiús), which is inherited from Proto-Hellenic *hūyús,[1] from Proto-Indo-European *suH-iu- (“son”).[2] Beekes suggests that the o-stem arose by dissimilation; the u-stem keeps both the full grade of its suffix (genitive υἱέος (huiéos)) and the zero grade (epic υἷος (huîos)).[2]

The same preform gave Tocharian B soy and Tocharian A se “son”,[2] and Wiktionary also compares Old Armenian ուստր (ustr).[1] Most other languages have the suffix Proto-Indo-European *suH-nu- instead, as in Lithuanian sūnùs, Old High German sunu and Avestan hunu (“offspring”).[2] Both are probably derived from *suH- (“to bring forth”), so that the word first meant “produce of the body”.[2] Beekes notes that “son”, unlike the words for father, mother, daughter and brother, lacks the suffix *-ter-, and suggests that it replaced an older word for “son”.[2]

Ancient writers derived it from ὕω (húō, “to rain”) (Plutarch) or from φύω (phúō, “to beget”) (the Homeric Epimerismi).[6]

Earliest recorded meaning

The word is already on the Mycenaean tablets as Mycenaean Greek i-jo.[2] In Homer it means a son; in the plural with the name of a people it stands for the people itself, so that “the sons of the Achaeans” are simply the Achaeans.[3][5]

Semantic evolution

In some dialects, including the Ionic prose of Herodotus, παῖς (paîs) takes its place, and it is rare in tragedy.[3] Menander uses it figuratively, “son of pain”.[5]

The Septuagint has many Hebrew-style periphrases with it: “a son of a hundred years” is a man a hundred years old, and “sons of injustice” are unjust men; the New Testament has “a son of peace” in the same way.[3] In the New Testament it also means a descendant of a famous ancestor, a disciple or follower, and the young of an animal, and it is used of Jesus as “the Son of Man”.[5][7] The Hellenistic compound υἱοθεσία (huiothesía, “adoption”) grew out of the phrase “to make someone one's son”.[2]

Modern Greek keeps υιός (yiós) as a learned word (in company names, “and Sons”) and in theology for the Son, the second person of the Trinity; the everyday word is γιος (gios).[8][1]

  • 1st century AD – The New Testament uses it of followers and descendants, and of Jesus as the Son of Man.[5][7]
