siglum

Learned borrowing from Late Latin siglum (“abbreviation”), possibly a contracted form of:

• sigillum (“figurine, statuette; seal”), from signum (“figure, statue; seal, signet; mark, sign”) (ultimately from Proto-Indo-European *sek- (“to cut, sever; to cut off”) or *sekʷ- (“to follow”)) + -ulum (diminutive suffix);^[1] or
• singulum, a singular form of singulus (“apiece; every; single”, adjective), ultimately from Proto-Indo-European *sem- (“one; together”).^[2]

The plural form sigla is a learned borrowing from Late Latin sigla.
