The suffix that turns a thought into a movement, or a movement into a prison.

means A suffix attached to a root word to name a distinctive system of belief, practice, or behavior — turning an idea, a person's name, or a quality into the label for a whole doctrine.

from Traced back through Latin -ismus to Greek -ismos, a noun-forming suffix that turned verbs ending in -izein into nouns naming the action or practice itself. Greek used it for things like 'baptismos' (baptizing) — the doing of a thing, crystallized into a name. English inherited the suffix piecemeal through borrowed words like 'baptism' and 'criticism,' then, once the pattern was felt as a unit, began bolting it onto almost anything — names (Darwinism), nationalities (Americanism), even itself, since 'ism' eventually became a free-standing noun meaning 'a doctrine or practice,' used dismissively as in 'don't give me your isms.'
