Morphology

informant = inform (transparent) = inform + ant

Standard agentive formation: 'inform' + '-ant' denotes 'a person who informs', so the meaning is directly derived from the verb.

Etymology

Informant comes from the verb inform, which comes from old words meaning 'to make known' or 'to give form'. So an informant is a person who 'gives' information to others, often secretly or to the police.
