fresh

The root fresh is one of those plain, everyday Germanic words that has been in English since before the Norman Conquest. It comes from Old English fersc, which originally did not mean "new" at all — it meant "not salt, not preserved." Fersc water was water you could drink, as opposed to seawater; fersc meat was meat that had not been salted or smoked to keep it. The whole point of the word was contrast with anything cured, pickled, or gone stale.

From that starting image — food and water that has not been treated or spoiled — the meaning naturally widened. If fresh meat is meat that is still in its original good state, then bread can be fresh, paint can be fresh, air can be fresh, and even an idea or a face can be fresh. By Middle English the word had absorbed the borrowed sense "new, recent" (reinforced by Old French freis / fresche, itself borrowed back from Germanic), so today fresh covers a whole cluster: not stale (fresh bread), newly done (freshly painted), cool and clean (fresh air), and new on the scene (a fresh start, a freshman).

Because fresh is a native Germanic root, it builds its family with plain English endings rather than Latin prefixes:

- fresh + -en (make) -> freshen: to make or become fresh again
- fresh + -ly (manner) -> freshly: in a newly-done way (freshly baked)
- fresh + -ness (state) -> freshness: the quality of being fresh

The one prefix that matters here is re- (again): re- + fresh -> refresh, "to make fresh again." That gives the whole sub-family refreshing (making you feel new again), refreshment (a snack that restores you), and the very modern computing sense "refresh the page" — load it again so it shows new content. Notice the pattern: every refresh- word is about restoring something to its fresh state, whether that is a tired person, a stale memory, or an out-of-date screen. The root stays homely and concrete; the meanings just keep circling back to that first image of something clean, new, and not spoiled.
