means A person who supplies information, especially someone who secretly gives authorities details about others' wrongdoing.
from From Latin informare, 'to shape, form, instruct,' which gave English 'inform' — literally to put form or knowledge into someone's mind. 'Informant' is the one who does the informing, with the agent suffix '-ant' (also Latin, marking the doer). The word arrived in English by way of legal and administrative Latin, and its sense narrowed over time from any 'one who informs' to the more loaded figure of one who informs *on* others.
