An obsolete or dialectal term, possibly referring to a sign or signal related to ants, or an archaic medical/scientific designation.
Possibly from French or Medieval Latin combining 'ant' with 'signe' (sign), though this term is extremely rare and its exact etymology and usage are uncertain in modern sources.
This word is so obscure that it barely appears in historical records—it's the kind of term that reminds us that language has vast graveyards of forgotten words that once meant something specific to someone but have completely disappeared from use.
