Pronunciation
Forms
signum n (genitive signī); second declension[1] Georges records an Old Latin seignom, and Köbler the medieval spellings singnum and cignum.[2][3]
Etymology
It is inherited from Proto-Italic *sekno- (“statue, sign”), inherited from Proto-Indo-European *sek(h₂)-no- (“cut”), a derivative of Proto-Indo-European *sek- (“to cut”), the root of secāre, so that the original sense was “what is cut out or carved”; the OLD likewise analyses it as the verb with the suffix -num.[4][5][1] Cognate with Marrucinian asignas (“cut meat”) and Oscan segúnú (“statue”), with the Oscan verb seganatted “marked”, and perhaps with Marsian seino (“statue”).[4] De Vaan notes that, since a laryngeal in the root would have left an unsyncopated vowel, the derivative may have been formed from the Italic root at a late stage.[4]
Wiktionary and Etymonline report Watkins's alternative, Proto-Indo-European *sekʷ-no- “standard that one follows”, from Proto-Indo-European *sekʷ- (“to follow”).[1][6] Lewis and Short compared a Sanskrit root meaning “to cling to”.[7] Sigillum is the diminutive *segno-lo- “small sign”, and sīgnāre and īnsīgnis are derived from the noun.[4]
Earliest recorded meaning
It is attested from Naevius onwards.[4] In Plautus it already means a seal, a distinguishing mark, a recognition token, a statue and a constellation, and Ennius uses it of an omen and of the starter's signal at the games.[5]
Semantic evolution
Its basic sense was a mark made to show position or ownership, hence a seal or signet, a distinguishing feature, the tokens by which an exposed child was recognized, a nickname, and a mark on the body.[5][7] It then meant any indication from which something is inferred: presumptive evidence in rhetoric, a weather sign or symptom, an omen, a trace, a gesture, a military signal, a password, a symbol, a shop sign.[5]
The military standard was a signum, and the plural signa stood for active service (sub signis), for allegiance to a commander and for the lines of an army, and by metonymy a signum was a maniple.[5] Another group of senses is the carved or cast figure: a statue, a figure in relief or in a painting, and a constellation or sign of the zodiac.[5][8]
Christian Latin used it for a miracle and for the sign of the cross, which Lactantius calls signum crucis;[1][9][2] medieval texts have it for a king's monogram, a hand-mark, a milestone or boundary mark, a gesture of monastic sign language, a battle cry, and the ringing of a bell or the bell itself, whence Portuguese sino “bell”.[10][3][1] The Romance languages keep it as Italian segno, French seing and signe, Spanish seña and Romanian semn,[1] and English sign came through Old French in the early 13th century, first as a gesture of the hand.[6]
