Etymology

The word "staple" originates from Old English stapol, meaning "post" or "pillar," reflecting its early use in structural contexts. Over time, it evolved to denote a fastener (resembling a small post) and later expanded metaphorically to mean a "principal commodity" (as in a market's central pillar). The suffix -le likely functioned as a diminutive or frequentative, emphasizing smallness or repetition.
