- store (v.)
- mid-13c., "to supply or stock," from Old French estorer "erect, construct, build; restore, repair; furnish, equip, provision," from Latin instaurare "restore, renew, repair, make," in Medieval Latin also "to provide, store," from in- "in" + -staurare, from PIE *stau-ro-, suffixed extended form of root *sta- "to stand" (see stet, and cf. restore). The meaning "to keep in store for future use" (1550s) probably is a back-formation from store (n.). Related: Stored; storing.
