Quiz: Remember the definition of mal de mer?
"turf, stretch of grass," 1540s, laune "glade, open space between woods," from Middle English launde (c.1300), from Old French lande "heath, moor, barren land; clearing" (12c.), from Gaulish (cf. Breton lann "heath"), or from its Germanic cognate, source of English land (n.). The -d perhaps mistaken for an affix and dropped. Sense of "grassy ground kept mowed" first recorded 1733.
"thin linen or cotton cloth," early 15c., probably from Laon, city in northern France, a center of linen manufacture. The town name is Old French Lan, from Latin Laudunum, of Celtic origin.
