procedo

Procedo, procedere, processi, processum, third conjugation, pro plus cedo: to step forward. Literal in a chronicle, where an army procedit out of camp, and figurative everywhere else, where an affair procedit bene or male and means it turned out well or badly.

Theology gives it its heaviest load. The Filioque quarrel that split the Latin and Greek churches turns on a single clause - qui ex Patre Filioque procedit - and on whether the Spirit proceeds from the Son as well as the Father; processio is the technical noun for it. The same stem gives English process, procession, proceeds and proceedings, all of them keeping the sense of moving forward in an orderly line, which is more than can be said for most legal proceedings.
