Etymology
It is borrowed from Old French enforcier (“to exert force”) and enforcir, to strengthen,[2][3][4] from Late Latin *infortiāre, *infortīre,[2][4] from in-, in, and fortis, strong (see force).[2][3][5]
Earliest recorded meaning
To make an effort: probably about 1343;[2] to strengthen a fortress, 1340–70 in the OED;[6] to drive by physical force, the mid-14th century in Etymonline.[3]
Semantic evolution
To force or compel is from 1350.[2] In the late 14th century it also meant to reinforce, strengthen an argument, and grow stronger,[3] and to press home or emphasize from the 15th century.[4] The meaning to compel obedience to a law is attested from the 1640s.[3] Enforcement is from 1475, in Caxton,[2] and enforceable from 1589.[2] The NODE notes it was formerly also written inforce.[5]
