What does conn mean?
Conn is a specialized nautical term meaning to direct the steering and course of a ship, usually by issuing commands to the helmsman rather than holding the wheel oneself. It functions both as a verb — 'the captain conned the ship through the strait' — and as a noun in phrases like 'take the conn' or 'have the conn', which denote assuming formal responsibility for the vessel's movements. The usage is rooted firmly in naval practice, where command authority is deliberately explicit: exactly one person holds the conn at any moment, and the transfer of that responsibility is announced aloud on the bridge. The word is rare outside maritime settings, though it enjoys familiar currency among fans of naval fiction and science fiction, most famously Star Trek. For general readers, encountering 'conn' is a reliable signal of a seafaring context and of the disciplined hierarchy aboard a warship or large merchant vessel.
To direct or take charge of the steering of a ship, giving orders to the helmsman.
"The captain conned the frigate through the minefield with great care."
The act, office, or duty of directing a ship's course and steering; also, by extension, the officer exercising that control.
""You have the conn," the admiral said, leaving the young officer in charge of the ship's movements."
On a warship, 'having the conn' is such a big deal that officers formally announce when they assume or surrender it — the phrase even opens dialogue aboard Star Trek's Enterprise.

Etymology of conn
Conn arose in English in the 17th century, apparently as a shortened or altered form of the obsolete verb 'cond', itself derived from 'conduct', which traces back through Old French conduire to Latin conducere, 'to lead or bring together'. Its history is bound up with naval command practice, where the officer directing the ship's steering 'conns' the vessel. Related words sharing the Latin root ducere include conduct, conductor, and conducive.
How conn is actually used
Strictly nautical register, used almost exclusively in naval and maritime contexts. In naval tradition, only one person has the conn at a time, and assumption or relinquishment of the conn is formally declared aloud.
