pinned

1. 1
   verb

   Simple past and past participle of pin.

   He pinned the wrestler to the mat in the final round.

   The photographs were pinned along the hallway wall before the exhibit.

   Note

   One spelling does double duty. In she pinned the notice up it is the past tense; in the notice was pinned up or has been pinned it is the participle after be or have. The final n doubles before -ed. Every use of pin carries over, so a chess piece, a message or app, and a security certificate can all be pinned.

2. 2
   adjective

   Equipped with a specified number or kind of pins.

   Older electronics often used round-pinned connectors that newer ports later replaced.

   The antique cabinet's hinges were brass-pinned for extra strength.

   Note

   Here the word describes how a thing is built, not what someone did to it. It usually closes a hyphenated compound whose first part supplies the count or kind: a three-pinned arch, a brass-pinned hinge. Because it names a fixed feature, it has no comparative. Keep it apart from the past participle: a three-pinned arch has three pins, but nobody has pinned it.
