Morphology

fixator = fix (semi-transparent) = fix + ator

Formally 'fix' + agentive suffix yields 'one that fixes', but the anatomical meaning ('a muscle that stabilizes') is specialized and may not be obvious to average learners.

Etymology

Fixator comes from an old Latin word fixare meaning 'to fasten' and the ending -ator that makes it 'a thing that does' the action. So, a fixator is something that holds or fixes a part firmly in place, which is why in the body a fixator is a muscle that keeps a joint steady during movement.
