Origin:
Heraldic couchant ("lying down with the head up") is late 15c, from the French present participle of couch c1300, 'to spread or lay on a surface, to overlay,' from Old French couchier 'to lay down, place; go to bed, put to bed,' from Latin collocare 'to lay, place, station, arrange,' from assimilated form of com 'with, together' + locare 'to place,' from locus 'a place' (Online Etymology Dictionary)
