Surface Forms

Morphology

restrictor = restrict (transparent) = restrict + or

Productive derivation: '-or' forms a noun denoting an agent, instrument, or regulator from the verb 'restrict', matching the sense 'something that limits or controls'.

Etymology

Restrictor comes from the Latin parts re- 'back' and stringere 'to draw tight', the same root as strict, which gives the image of binding something. So a restrictor is a rule, device, or person that 'binds back' or limits an activity, access, or freedom.
