Etymology
It is inherited from Proto-Germanic *būaną (“to live, dwell”),[2][1] a cognate of Gothic 𐌱𐌰𐌿𐌰𐌽 (bauan), Old English būan, Old Saxon būan and Old High German būan (“to live, dwell; to build”).[2][3] Kroonen explains the variation between “*bōan-” and “*būan-” in Germanic as an old ablauting present of Proto-Indo-European *bʰeh₂u-, the full grade giving “*bō-” and the zero grade “*bū-”.[2] The root is that of Latin fuī (“I was”), Ancient Greek φύω (phúō, “to bring forth”) and Lithuanian būti (“to be”), meaning “to grow, come into being, be”.[4][5] Ásgeir Blöndal Magnússon suggests that the sense “to adorn, equip” may go back to a compound with “*bi-”.[4]
Earliest recorded meaning
Viking Age runestones already use the past tense of “dwelling”: Þeir bjoggu báðir í Báristǫðum “they both lived in Báristaðir”.[6] The first dated record is ONP's citation of 1192, in the sense “prepare”: þaɴ dág bio maria magdalena guþ. til graftar “that day Mary Magdalene prepared God for burial”.[7] The sense “dwell” follows in a manuscript of about 1200: Sę́ler ero þeir drótteɴ er bua i húse þíno “blessed are they, Lord, who dwell in your house”.[7]
Semantic evolution
Lexicon Poeticum takes “to be” as the basic meaning, from which the others grew.[8] ONP's commonest sense is “live, dwell”, often as the head of a household, followed by “prepare, make ready” and “live with (someone), lie with”; it also has “run a farm, keep house”, the use on board ship, and the opening formula of tales.[7] The past participle búinn “ready, prepared” is used much as an adjective.[7][9] In law the verb means “to be a householder”.[10]
The reflexive búask “to make oneself ready” was borrowed into Middle English as busken, English busk.[5][11] The verb continues as Icelandic búa, Faroese búgva, Swedish bo and Danish bo.[4]
