dos n (plural dosuri)[1]

Etymology

It is inherited from Vulgar Latin dossum (“back”), the popular form of Latin dorsum (“back”).[2][3][4][5][1] De Vaan explains the ⟨ss⟩ as a late assimilation of /rs/, and derives the Latin noun from a compound meaning “turned away”, the source of deorsum (“downwards”) too.[6][3]

Of the sister branches, the sources record only Istro-Romanian dos.[2][3][7] The Romance cognates include Dalmatian duas, Italian dosso, French dos, Occitan dos and Catalan dos.[2][8] dosar “file” is a later borrowing of French dossier, a derivative of the French word.[2]

Earliest recorded meaning

The first record is in a Wallachian charter of 1519.[3][9][4] MDA2 gives as its first source the Teachings of Neagoe Basarab.[10]

Semantic evolution

The old sense “back of a person” is now dated or popular; ordinary speech uses spate instead.[4][1] The Bucharest Bible of 1688 still has it: Shem and Japheth „să dusără cu dosul înainte” “went backwards”.[4]

From the back of the body it came to mean the rear or reverse side of anything: the back of a house, the reverse of a page, the inside of a garment, the back of the hand.[3][11] In the countryside dos is a sheltered place out of the sun, especially a north-facing slope.[3][12] A da dosul “to turn one's back” meant “to flee” as early as Neculce, and pe dos is “inside out, the wrong way round”.[9][11] The verb dosi “to hide; to steal” and the adjective dosnic “hidden, out of the way” are Romanian derivatives.[3][2]
