refresher

the word 'refresher' is built upon the verb 'refresh', which entered middle english from anglo-french 'refrescher', itself a combination of the latin prefix 're-' ('again') and the old french 'fresche' ('fresh'). the core root 'fresh' has germanic origins, traceable to the proto-germanic 'friskaz', meaning 'unsalted, new'. the addition of the agent suffix '-er' transforms the action into a noun denoting something that performs the act of making fresh again. thus, the literal logic of 'one who or that which makes fresh again' evolved from its concrete origins to describe both restorative objects and, metaphorically, educational courses that renew one's knowledge.
