Origin & History of “staple”

English has two distinct words staple, but they come from a common ancestor – prehistoric Germanic *stapulaz ‘pillar’. this evolved into English staple (OE), which at first retained its ancestral meaning ‘post, pillar’. The modern sense ‘U-shaped metal bar’ did not emerge until the end of the 13th century, and the details of its development from ‘pillar’ are obscure. The middle Low German and Middle Dutch descendant of *stapulaz was stapel, which had the additional meaning ‘market, shop’ (presumably from the notion of a stall situated behind the ‘pillars’ of an arcade). This was borrowed into Old French as estaple, which in turn gave English staple ‘market’ (15th c.), hence ‘principal commercial commodity’.
