Forms
rasoir m (plural rasoirs)[1] Old French rasuir (mid-12th century), rasouer (about 1180), then rasoir.[2] Benoît de Sainte-Maure writes rasor about 1160.[3] Anglo-Norman rasour, rasure, rasuir.[4]
Etymology
It is inherited from Old French rasuir, inherited from Late Latin rāsōrium (“razor”).[2][1][5] The Late Latin noun is formed on rāsum, the supine of Latin rādō (“to scrape, shave”).[2][3] The TLFi finds the Late Latin noun with the sense “razor” in the Itala, while Bloch and Wartburg and the GLLF give its late Latin sense as “graving tool, burin”.[2][6][3] In French terms it can also be analysed as raser with the suffix -oir.[1]
Cognate with Italian rasoio, Catalan rasor and Occitan razor.[7][8] Meyer-Lübke notes that it displaced the older Latin novāculum.[7]
Earliest recorded meaning
It is first found as rasuir in the Cambridge Psalter, in the middle of the 12th century, meaning an instrument for shaving.[2] A 13th-century psalter has the comparison Tu es si comme rasoirs aguz qui est tranchanz “you are like a sharp razor that cuts”.[8]
Semantic evolution
The razor's sharpness gave the comparison couper comme un rasoir “to cut very well”, recorded by the Académie in 1740, and the stone and leather used to hone it gave pierre à rasoir (1717) and cuir à rasoir (1869).[3][8] During the Revolution the word was applied to the guillotine (1792), also called rasoir national by Camille Desmoulins in 1793–94.[2]
In slang it came to mean a tedious person (Delvau, 1866).[2] Since 1881 it has also been an adjective, “boring”,[2] but the BHVF and the FEW date the phrase ça fait rasoir with this sense as early as 1790.[9] The 20th century added new kinds of razor: the mechanical or safety razor with a removable blade (1904–1907) and the electric razor (about 1945).[3] English razor came from the Old French word around 1300.[10]
