Other forms: processions
A procession is a line of people walking together in ceremony. A funeral procession, the procession moved off, a torchlight procession.
The order of the line is usually the whole point — who walks where says something. Religious, civic and funeral processions are the common kinds, and a carnival procession is the loud one. Figuratively, a procession is a steady succession: a procession of visitors, a procession of bad decisions. In sport, a procession is a race with no overtaking, which is a complaint rather than a description.

Too few real examples of this word to estimate which sense is commonest.
procession is a moving line.
Latin processio means a marching forward, from procedere — pro-, forward, plus cedere, to go. Proceed, process and procession are the same verb, so a procession is simply people proceeding.
