baas m (plural bazen, diminutive baasje n, feminine bazin)[1]

Etymology

It is inherited from Middle Dutch baes, from a Germanic base that the EWN reconstructs as Proto-Germanic *basa-, of unknown origin.[2][3][4][5] Its relatives are late Middle Low German bās (“overseer of dike works”) and Old Frisian bas (“master”) (modern West Frisian baas); Van Haeringen takes the Low German word as a borrowing from Dutch.[2][6] No cognates are known in other Indo-European languages, and the EWN thinks it is probably a word from a non-Indo-European substrate.[2] Wiktionary reconstructs Old Dutch *baso (“uncle, kinsman”) and Proto-Germanic *baswô (“paternal uncle, kinsman”), perhaps related to Proto-Germanic *bō- (“father, older male relative”).[1]

A link with Old High German basa (“father's sister”) (modern German Base “female cousin”) has often been proposed; the EWN calls it doubtful and Franck–Van Wijk improbable.[2][5][3] Bugge explained ⟨basa⟩ as a nursery shortening of a compound of “father” and “sister”, and the WNT and Vercoullie allowed that ⟨baas⟩ could have been formed in the same way from a compound with “father”.[7][8] Holthausen's derivation from a compound ⟨*bātesman⟩, with baat “profit”, is improbable.[6] A comparison with ⟨bassa⟩ “pasha” was dismissed as early as 1856.[7]

Earliest recorded meaning

The word first appears as a personal name: pieter.f. baes in Bruges in 1280, and baes van dauerlo among the aldermen of Bruges in 1293; the VMNW takes it as a Middle Dutch form of the Germanic man's name Baso.[9][2][10] As a common noun it is first found in ten base “to the head of the family” (1380–1425), where young wolves run to the master of the house to eat.[2][11]

Semantic evolution

The original sense, the WNT says, was the head of a household, to whom the whole household, its animals included, was subject;[7][2][5] Kiliaan glosses it as herus, paterfamilias, and the EWN gives his sense as “friend and master, head of the family” (1599).[7][2][5] The word was very rare in Belgian Middle Dutch but common in Holland and in Low German.[7]

From the head of the household it became a word for addressing an older man, later only one of lower rank (1623), and in the diminutive baasje a little boy (1857) or a little elderly man; because the household's animals also had a master, it came to mean the owner of an animal, especially a dog (1800).[7] De vrouw is baas, “the wife is the boss”, of the one who rules the house, is recorded in 1784.[7] Today it is anyone in authority, an employer, the owner of a business or of a pet.[12][13]

English took the word in North America: work base “foreman” is recorded in 1649 and the basses house in 1653, and the spelling boss from 1803, on the model of words whose ⟨o⟩ American English pronounces unrounded.[2] Etymonline records Dutch baas in English from the 1620s as the title of a Dutch ship's captain.[14] The word also went to German Baas in seafaring, to Danish, Norwegian and Swedish bas “foreman”, and through Afrikaans to English baas.[15][2][3]
