Cognate with Spanish res. Origin contested. From either Latin rēs (“thing, property”) or Arabic رَأْس (raʾs, “head”, also of cattle). While the latter is a perfect semantic match, the front vowel of the Romance form speaks against Arabic origin because dialects generally maintain a back -a- in this word (compare Maltese ras, not *ries).
rês f (plural reses)
- neat (food animal)
