Origin & History of “plank”
The etymological idea underlying plank may be ‘flatness’. It comes via planke, a northern dialect version of Old French planche (source of English planchette (19th c.)), from late Latin planca ‘slab’, a derivative of the adjective plancus ‘flat’. this may have come from the same source as Greek pláx ‘flat surface’, ancestor of English placenta.
