Refreshen comes from re- ('again') + freshen, from fresh + -en. Fresh is from Old English fersc ('fresh, unsalted'), from Proto-Germanic *friskaz. The historical chain includes Latin re-, Old English fersc, and Proto-Germanic *friskaz. Older glosses in the chain include "again" and "fresh, unsalted", which help explain the semantic range of the modern word. Morphologically, refreshen is best read as compound, suffixal formation, and borrowing, yielding an English verb shaped by both form history and later usage. In current English it functions as a verb, with the sense "to make fresh again; to revive or invigorate". English derivatives include refreshened and refreshening; related forms include refresh, freshen, and fresh. The result is an English verb whose etymology preserves the older forms while supporting the word's specialized modern meaning.
