What's the difference between i.e. and e.g.?
late 14c., from Old French patin "clog, type of shoe" (13c.), probably from pate "paw, foot," from Gallo-Romance *pauta, ultimately perhaps imitative of the sound made by a paw. The immediate source has been sought in Celtic [Barnhart] and Germanic [OED], but evidence is wanting. Likely cognates include Provençal pauta, Catalan pote, Middle Dutch and Dutch poot, German Pfote "paw."
