At or towards the stern or after part of a ship, as a word describing either position or motion. A gun may be mounted aft (an expression of position), and seamen sent aft to man it (an expression of motion), while fore and aft means from stem to stern. Aft is a contraction of abaft, though used in a general, not relative, sense. The adjective is after, e.g. the after part of a ship, as above.
