invent: [15] Invent originally meant ‘find’ (‘Since that Eve was procreated out of Adam’s side, could not such newels [novelties] in this land be invented’, wrote the anonymous author of a 15th-century song). It was based on invent-, the past participial stem of Latin invenīre ‘come upon, find’, a compound verb formed from the prefix in- ‘on’ and venīre ‘come’.

The sense ‘devise’, which developed via ‘discover’, actually existed in the Latin verb, but English did not take it on board until the 16th century. The derivative inventory [16] was borrowed from medieval Latin inventōrium ‘list’, an alteration of late Latin inventārium, which originally meant a ‘finding out’, hence an ‘enumeration’.
