Morphology

operator = operate (semi-transparent) = operate + or

Built from 'operate' + '-or' but the technical mathematical sense is specialized and may not be obvious to a B1 learner.

Etymology

Operator comes from the Latin root oper-, the same root in operate and operation, which means 'to work' or 'to do'. In math an operator is like a little worker that 'does' an operation on numbers, so the name fits its job.
