Unknown, probably Celtic or from a Pre-Celtic substrate,[1] perhaps from Proto-Indo-European *tewk- (“to swell; fat”).[2][3] Cognate of Umbrian toco (“liquid lard”) and Gaulish tuccus (“back”).
tucca f (genitive tuccae); first declension[2]
This word appears in the Latin–Greek glossary of Pseudo-Philoxenus with the Greek gloss κατάχυμα ζωμοῦ (katákhuma zōmoû, “lard sauce”).[5]
