Surface Forms

tester singular

Morphology

tester = test (transparent) = test + er

The meaning is directly compositional: a tester is something or someone that tests.

Etymology

Tester meaning a device or person that checks something is also from test + -er and so means 'one who checks'. That's why a tester can be a person checking products or a tool that checks if a machine, circuit, or program really works.
