Morphology

subluxation = luxation (transparent) = sub + luxation

The medical prefix 'sub-' (partial/under) attaches to the noun 'luxation' to indicate a lesser degree of dislocation, a directly compositional medical formation.

Etymology

The word subluxation comes from sub- meaning 'under' or 'less' and luxation meaning 'a dislocation'. So a subluxation is a 'partial' dislocation — the joint is a bit 'out of place' rather than fully dislocated.
