Etymology

It is inherited from Middle English concluden, borrowed from Latin conclūdō (“to shut up, enclose, end”),[2][3][4][5][6] from com- (“completely, together”) and claudō (“to shut”) (see close).[2][3][4][6]

Earliest recorded meaning

To shut off or win an argument: before 1325, in Cursor Mundi, in Barnhart; the early 14th century in Etymonline.[2][3]

Semantic evolution

To reach a conclusion, to infer, is from about 1380, in Chaucer's Boethius,[2] the late 14th century in Etymonline.[3] To bring to an end is also from the late 14th century,[3] or before 1420 in Barnhart.[2] To enclose or include, now obsolete, is from about 1386,[7] to bind to a course of action from 1393,[7] and to settle or arrange finally, as a treaty, from the early 15th century.[3] Conclusion is probably from about 1370, in Chaucer.[2] In Yorkshire, Kent and Surrey dialect to conclude was to decide or arrange.[8]
