Support verb constructions are documented throughout the history of Latin. These syntagms are characterized by the presence of a support verb with a more or less reduced semantic force, and a predicative (abstract or verbal) noun that often constitutes its direct object. The present contribution deals, specifically, with the use of facio as a support verb (as in bellum facere, iter facere, insidias facere etc.), focussing on the post-classical and late period. Two main questions shall be discussed: (a) whether, and if so, how facio becomes more productive in later centuries in both non-Christian and Christian sources; (b) what type of semantic evolution the verb undergoes in later Latin and whether, in this respect, continuity or rupture should be assumed with regard to the earlier period. This last point will enable us to suggest a more convincing explanation of an often-quoted passage of Cicero (Phil. 3. 22), in which the expression contumeliam facere is found.
