The word "plank" traces back to Old French planke (flat piece of wood), derived from Late Latin planca, meaning "board" or "slab." The Latin term likely evolved from the Proto-Indo-European root plak- (to be flat), which also gave rise to words like "plate" and "plain." The Germanic influence reinforced the final -k sound, distinguishing it from related Romance terms. Historically, planks were essential in shipbuilding and housing, reflecting their practical and sturdy nature.
