Pronunciation

Forms

seing m (plural seings)[1] Old French sain, seign and saing.[2][3] In the sense of a signature it was also written sing (1538) and seng (1395).[4]

Etymology

It is inherited from Old French seing, inherited from Latin signum (“mark, sign, seal”).[5][4][6][7][1] It is a doublet of signe, borrowed from the same Latin word, and of tocsin.[1][4]

Cognate with Italian segno, Spanish seña, Portuguese senha, Catalan senya and Occitan senh.[7][8][3]

Earliest recorded meaning

In the Roman de Troie (about 1165) it is a mark, here a birthmark on the skin.[5][4]

Semantic evolution

Old French used seing for several kinds of mark: a mark bounding a wood where nets were set (about 1170, spelled sain), a target (about 1270), a mark stamped with a tool (1283) and the tool itself (1296).[4][2] Bloch and Wartburg add the sense “bell”, from Late Latin, the one kept in tocsin.[7] From about 1170 it also meant a mark put at the foot of a document to certify it,[5] and so a signature, the sense that held in the classical period and became the legal “signature that makes an act authentic” in 1373.[4][9]

Today it survives in law in seing privé (1660), the signature of a deed not drawn up before a notary, as in acte sous seing privé,[4][2][10] and in the compounds blanc-seing and contreseing.[7]
