The quality or state of being fresh; newness, vigor, or the pleasant quality of something that is cool or not stale.
From 'fresh' (Old French 'freis,' from Germanic root meaning 'new' or 'not salt') plus English suffix '-ness' meaning the state or quality of something.
The word 'fresh' originally meant 'not salty' in English—fresh water versus salt water—but it expanded to mean 'new' and 'not stale' because of the mental leap that unused things have a certain quality newness brings.
