Etymology

It is inherited from Middle English forte, borrowed from Middle French fort, a noun use of Old French fort “strong, fortified”,[2][3][4] from Latin fortis (“strong, brave”), from Old Latin forctus, of unknown etymology.[2][4] It is possibly from Proto-Indo-European *bhergh- (“high, elevated”), whose derivatives refer to hills and hill-forts.[2][3][5] Hoad adds Italian forte as a source.[6] It is related to fortify, fortress, force and forte.[2][3]

Earliest recorded meaning

A fortified place, a stronghold: the mid-15th century in Etymonline, 1435 in Barnhart, 1557–75 in the OED.[2][3][7] Barnhart has an earlier forte “courage” probably before 1375.[3]

Semantic evolution

A strong position in a figurative sense is from 1568,[7] and hold the fort from the 1590s.[2] The lair of a wild animal is from 1653.[7] In British North America and parts of the United States, a trading station, originally fortified, is from 1776.[7] The verb, to fortify, is from 1559.[7]
