Etymology

It is inherited from Middle English force (also fors), borrowed from Old French force (“force, strength; courage; violence, compulsion”),[2][3][4] from Late Latin fortia,[2][5] the neuter plural of Latin fortis (“strong, mighty; brave”),[2][3][5] which Klein notes was mistaken for a feminine singular noun.[6] The verb is inherited from Middle English forcen, from Old French forcier (“to conquer by violence”), from Vulgar Latin *fortiāre.[2][3][7] The AHD traces Latin fortis to Proto-Indo-European *bhergh- (“high”).[5] It is related to fort, fortitude, effort and comfort.[3][6]

Earliest recorded meaning

Physical strength, might: probably before 1300, in Arthour and Merlin,[2] or about 1300.[3][8]

Semantic evolution

The power or might of a ruler or realm, especially military strength, is recorded from 1303.[9] The power to convince the mind and power used against someone's will are from the mid-14th century.[3] A body of armed men is from the late 14th century,[3] or 1487 in the Historical Thesaurus,[9] and Hoad dates it to the 14th century.[10] The physics sense, an influence that changes a body's motion, came later.[3][11] The verb meant “to exert force upon an adversary” about 1300, and by the early 14th century also “to rape”.[3][8] “To compel, constrain” is from about 1400,[3][8] and “to bring about by unusual effort” from the 1550s.[3] In card games, “to make a player play a certain card” is from 1746, in whist.[3][8] Forcible is from about 1422,[2] and forceful from 1571.[2]
