joist: [14] Etymologically, a joist is a wooden beam on which boards ‘lie’ down. The word’s ultimate ancestor is the Latin verb jacēre ‘lie down’ (from which English also gets adjacent). Its neuter past participle jacitum was taken into Old French as a noun, giste, which denoted a ‘beam supporting a bridge’ (its modern French descendant, gîte ‘home’ – that is, ‘place where one lies down’ – is currently infiltrating English). Middle English took over the Old French word, which from the 15th century gradually began to change to joist.
=> adjacent - joist (n.)
- early 14c. (late 13c. in Anglo-Latin), from Old French giste "beam supporting a bridge" (Modern French gîte), noun use of fem. past participle of gesir "to lie," from Latin iacere "to lie, rest," related to iacere "to throw" (see jet (v.)). Notion is of wooden beam on which boards "lie down."
