Etymology
Origin of conclude
First recorded in 1250–1300; Middle English, from Latin conclūdere “to close, end an argument,” equivalent to con- con- + -clūdere, combining form of claudere “to close ”
Explanation
The verb conclude means two related things: coming to a decision, and bringing to a close. Conclude is related to the word close, which is related to an old Latin word for "barrier" or "bolt" — the kind you put on a door. When you conclude something, it's as though you're pulling a door shut and bolting it. If your girlfriend concludes an argument by leaving the room and slamming the door, you can conclude that she's angry at you.
