fresh (adj.1)
late 13c. "unsalted, pure, sweet, eager," metathesis of Old English fersc "unsalted," from West Germanic *friskaz (cognates: Old Frisian fersk, Middle Dutch versch, Dutch vers, Old High German frisc, German frisch "fresh").

Probably cognate with Old Church Slavonic presinu "fresh," Lithuanian preskas "sweet." The metathesis, and the expanded Middle English senses of "new, pure, eager" are probably by influence of (or in some instances, from) Old French fres (fem. fresche), from Proto-Germanic *frisko-, and thus related to the English word. The Germanic root also is the source of Italian and Spanish fresco. Related: Freshly; freshness.
fresh (adj.2)
"impudent, presumptuous," 1848, U.S. slang, probably from German frech "insolent, cheeky," from Old High German freh "covetous," related to Old English frec "greedy, bold" (see freak (n.)).
