What does pintle mean?
A pintle is a pin, peg, or pivot used to support or connect a moving part. Its best-known nautical sense is the stout pin at the lower end of a rudder, around which the rudder turns. In engineering, the term can refer more generally to a small pivot or fastening pin that joins two components while allowing rotation. Because a pintle is a small but essential fitting, the word tends to carry a precise, technical tone rather than the everyday flavor of “pin” or “peg.” It is nevertheless useful in maritime writing, boating instructions, hardware descriptions, and accounts of historical steering mechanisms. Knowing the term helps distinguish the fixed support from the movable part it carries and makes technical descriptions of rudders, hinges, gates, and articulated fittings easier to follow. The word is uncommon in general conversation, but once encountered it reveals the compact vocabulary used to name the small parts that make larger mechanisms work.

Where does pintle come from?
Pintle entered Middle English as "pintel," borrowed from Anglo-French or Old French "pintel," a diminutive of "pin." It therefore shares its origin with English "pin" and compounds built on that root, including "pintail," "pinwheel," and "pincushion." Its nautical use developed from the older general sense of a peg or pivot to refer especially to the fitting on which a rudder turns.
How pintle is actually used
This is a specialist term, used chiefly in nautical and engineering contexts. It is uncommon in everyday speech and sounds more technical than the general terms "pin" and "pivot."
