Word OriginMiddle English: via Old French from Latin complexio(n-) ‘combination’ (in late Latin ‘physical constitution’), from complectere ‘embrace, comprise’. The term originally denoted physical constitution or temperament determined by the combination of the four bodily humours; sense (1) (late 16th cent.) being a visible sign of this.
