'refreshable' originates from English, specifically formed from the verb 'refresh' + the suffix '-able' (denoting 'capable of' or 'susceptible of').

'refresh' changed from Old French 'refreschir' (also attested as 'refrescher') and from Vulgar Latin *refrescāre (or Latin elements meaning 'make fresh'), and through Middle English 'refreshen' eventually became modern English 'refresh'; the adjective 'refreshable' was formed by adding '-able' to that verb.

Initially it meant 'to make fresh again' (literal sense); over time the meaning broadened to include 'restore energy or strength' and, in technology, 'reload or update (displayed information)'.
