Forms

planche f (plural planches)[1] Old French plance (about 1155) and planche (about 1190), with the Picard and Norman form planke.[2][3][4][5]

Etymology

It is inherited from Old French planche, inherited from Late Latin planca (“board, plank”), recorded in the 4th century in Palladius.[6][7][8] The TLFi and Bloch and Wartburg take the Late Latin word to be a syncopated form of *palanca, from Latin palanga (“wooden roller, pole”), with the change perhaps helped by plānus (“flat”);[6][8][3] the Latin word is from Ancient Greek φάλαγξ (phálanx, “round log, phalanx”).[3][9][1] Ernout and Meillet, as Rey reports, see instead the substantivized feminine of plancus (“flat-footed”), a popular formation like mancus (“maimed”), belonging to the root of words for what is flat; even then the word may have partly merged with the form in pal-.[10][2]

Cognate with Old Occitan planca, Catalan planxa, Spanish plancha, Portuguese prancha and Walloon plang.[4] The English word plank comes from the northern Old French form planke.[11]

Earliest recorded meaning

The word is first recorded in Floire et Blancheflor (1150) in the sense “footbridge, small bridge made of boards”; the plain sense “flat piece of wood, longer than it is wide” follows in Wace's Roman de Rou (1160–1174).[6][10]

Semantic evolution

Already in Old French the board's shape gave the sense “long narrow strip of cultivated ground in a garden” (1293).[6][10] In the 16th century the word took the figurative sense “what makes a thing easier, an example” (1541, Calvin), from the board used as a support, reinforced later by planche pourrie “someone or something not to be relied on” and planche de salut “last resort” (1822), the plank a shipwrecked man clings to.[6][10]

Engraving took over the word for a plate of wood, then of metal, cut for printing (1585) and, by metonymy, for a print taken from it (1575); planche à billets “note-printing press” followed in 1837.[6][10] In the 18th century les planches became the boards of the stage, giving monter sur les planches (1761), and faire la planche “to float on one's back” is recorded in 1794.[6][10]

Later senses include a thin person (1874), especially a flat-chested woman (1899), the blackboard in school slang (1878) and a pupil's oral test at the board (1929), skis (1933), and sports boards such as the planche à voile (1975).[6][10]
