Morphology

informer = inform (transparent) = inform + er

Agent noun formed regularly from the verb 'inform' with the productive suffix '-er', so the meaning 'someone who informs' is directly derived.

Etymology

Informer comes from inform, which means 'to give information', plus the ending -er meaning 'a person who does something', so an informer is 'a person who gives information'. That's why today an informer usually means someone who secretly tells the police or an authority about crimes.
