Middle English: from Old French parc, from medieval Latin parricus, of Germanic origin; related to German Pferch ‘pen, fold’, also to paddock. The word was originally a legal term designating land held by royal grant for keeping game animals: this was enclosed and therefore distinct from a forest or chase, and (also unlike a forest) had no special laws or officers. A military sense ‘space occupied by artillery, wagons, stores, etc., in an encampment’ (late 17th century) is the origin of the verb sense (mid 19th century) and of park (early 20th century).
