storey

From Middle English story, via Medieval Latin historia (“narrative, illustraton, frieze”) from Ancient Greek ἱστορίᾱ (historíā, “learning through research”). The current sense arose from narrative friezes on upper levels of medieval buildings, esp. churches. Doublet of story and history. An alternative etymology derives Middle English story from Old French *estoree (“a thing built, building”), from estoree (“built”), feminine past participle of estorer (“to build”), from Latin instaurare (“to construct, build, erect”), but this seems unlikely since historia already had the meaning "storey of a building" in Anglo-Latin.
