late 14c., "warlike, of or pertaining to war," from Medieval Latin martialis "of Mars or war," from Latin Mars (genitive Martis), Roman god of war (see Mars). The sense of "connected with military organizations" (opposed to civil) is from late 15c. and survives in court-martial. Also, occasionally (with a capital M-), "pertaining to or resembling the planet Mars" (1620s). Related: Martially. Martial law, "military rule over civilians," first recorded 1530s.

late 12c., "formal assembly held by a sovereign," from Old French cort "king's court; princely residence" (11c., Modern French cour), from Latin cortem, accusative of cors (earlier cohors) "enclosed yard," and by extension (and perhaps by association with curia "sovereign's assembly"), "those assembled in the yard; company, cohort," from assimilated form of com "with, together" (see com-) + stem hort- related to hortus "garden, plot of ground" (from PIE root *gher- (1) "to grasp, enclose").
Both senses of the Latin word emerged in English. From the purely physical sense come "palace, residence of a sovereign" (c. 1200), "enclosed space connected with a building or buildings" (early 14c.), and the sporting sense "smooth, level plot of ground on which a ball game is played" (1510s, originally of tennis). Also "short arm of a public street, enclosed on three sides by buildings" (1680s), formerly noted for poverty or as business districts.
From the notion of "surroundings of a sovereign in his regal state" (c. 1200) comes the legal meaning "a tribunal for judicial investigation" (c. 1300, early assemblies for justice were overseen by the sovereign personally), also "hall or chamber where justice is administered" (c. 1300). As an adjective, "pertaining to a court," late 13c.
"one who attends the court of a sovereign," c. 1300, courteour (early 13c. as a surname), from Anglo-French *corteour, from Old French cortoiier "to be at court, live at court," from cort "king's court; princely residence" (see court (n.)).
late 15c., "well-mannered, courteous, having manners befitting a court," from court (n.) + -ly (1). Compare courteous. Meaning "pertaining to the court" is from late 15c. The elegant, polite, refined courtly love "highly conventionalized medieval chivalric love" (amour courtois) is attested from 1821. Related: Courtliness.
c. 1300, "vegetable garden," from Anglo-French curtilage, Old French courtillage, from Old French cortil "little court, walled garden, yard," from Medieval Latin cortile "court, yard," from Latin cortis (see court (n.)). In later use principally a legal word for "the enclosed land occupied by the dwelling and its yard and out-buildings."
"medieval martial arts contest," c. 1200 (figurative), c. 1300 (literal), from Old French tornement "contest between groups of knights on horseback" (12c.), from tornoier "to joust, tilt, take part in tournaments" (see tourney). Modern use, in reference to games of skill, is recorded from 1761.
