What does captain mean?
A captain is the person who commands a ship or aircraft and bears ultimate responsibility for the vessel, its crew, and everyone aboard — a role so central to maritime life that the word has become shorthand for leadership itself. Beyond the sea and sky, captain names the elected leader of a sports team, a commissioned officer rank between lieutenant and major in many armies and air forces, and, figuratively, any dominant figure, as in 'captains of industry.' It also works as a verb: one can captain a cricket side or a fishing boat. The word derives from the Late Latin capitaneus, meaning 'chief,' itself rooted in caput, 'head,' which links it etymologically to words like capital and per capita. Its enduring connotations are authority, accountability, and the weight of command — the sense that when things go wrong, the captain answers first.
The officer in command of a ship, aircraft, or other vessel; the leader of a sports team; or a commissioned officer of intermediate military rank.
"The captain gave the order to abandon ship."
In naval usage, 'captain' can denote both a specific rank and the functional role of commanding a vessel.
To act as the captain of a ship, aircraft, or sports team; to lead or command.
"He captained England in over fifty Test matches."
Standard English plural, used for multiple commanders, team leaders, or officers holding the rank.
"All the captains gathered on the bridge for the briefing."
Every word that starts with 'cap-' — capital, capitol, decapitate — traces back to the Latin for 'head', and 'captain' is literally 'the head one'.

Etymology of captain
Captain entered English from Old French capitaine, borrowed from Late Latin capitaneus meaning 'chief' or 'principal,' which derives from caput, the Latin word for 'head.' This makes it a cousin of words like capital, capitol, and per capita, all built on the same root idea of 'head' or 'top.' The term was established in English by the late Middle Ages, originally denoting a military commander before becoming firmly attached to those who commanded ships at sea. Related Romance forms such as French capitaine and Spanish capitán preserve the same lineage.
How captain is actually used
In the British Royal Navy, 'captain' is a senior rank, while in the US Navy it is also senior; but in the merchant marine and most other navies, 'captain' refers specifically to the person in overall command of a vessel regardless of formal rank. Addressing someone as 'Captain' is a conventional courtesy aboard ships even if their official title differs.
