Morphology

thruster = thrust (transparent) = thrust + er

Formed by adding productive agent/instrument suffix '-er' to 'thrust', yielding an instrument that produces thrust.

Etymology

Thruster comes from the verb thrust meaning 'push' and the ending -er meaning 'one who' or 'thing that does'. So a thruster is literally 'a thing that pushes', which is why a small rocket engine that moves a spacecraft is called a thruster.
