fresh (adj.1)youdaoicibaDictYouDict
c. 1200, fresh, also fersh, "unsalted; pure; sweet; eager;" the modern form is a metathesis of Old English fersc, of water, "not salt, unsalted," itself transposed from Proto-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."

Sense of "new, recent" is from c. 1300; that of "not stale or worn" is from early 14c.; of memories from mid-14c. The metathesis, and the expanded Middle English senses of "new," "pure," "eager" probably are by influence of (or from) Old French fres (fem. fresche; Modern French frais "fresh, cool"), which is 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. Fresh pursuit in law is pursuit of the wrong-doer while the crime is fresh.

Old English grene, Northumbrian groene "green, of the color of living plants," in reference to plants, "growing, living, vigorous," also figurative, of a plant, "freshly cut," of wood, "unseasoned" earlier groeni, from Proto-Germanic *gronja- (cognates: Old Saxon grani, Old Frisian grene, Old Norse grænn, Danish grøn, Dutch groen, Old High German gruoni, German grün), from PIE root *ghre- "grow" (see grass), through sense of "color of growing plants."

From c. 1200 as "covered with grass or foliage." From early 14c. of fruit or vegetables, "unripe, immature;" and of persons, "of tender age, youthful, immature, inexperienced;" hence "gullible, immature with regard to judgment" (c. 1600).
