  • Ecclesiastical: [for.ti.fiˈkat.t͡si.o][1]

Forms

fortificātiō f (genitive fortificātiōnis); third declension[1]

Etymology

It is formed from Latin fortificō (“to strengthen, fortify”) + -tiō,[1][2] a verb made from fortis (“strong”) and faciō (“to make”).[3]

Earliest recorded meaning

It is post-classical:[4] the first author to use it is the medical writer Caelius Aurelianus (5th century AD), for strengthening that is to be applied to the body.[4][5][3]

Semantic evolution

Medieval Latin used it for strengthening in general, for a state of strength, and for proof or demonstration.[6] From the 13th century it also meant the fortification of a place against attack:[7][6] an English record of 1209 grants revenues for enclosing and fortifying a town.[7] In a 14th-century chronicle it is the growing force of blows on a door.[8]

English took it over in the early 15th century as fortification, through Old French.[2]
