What does informer mean?
An informer is someone who provides information, particularly to police, a government, or another organization. The term can refer neutrally to a confidential source, but it frequently carries negative associations with secrecy, betrayal, and divided loyalty. Informers may supply evidence, provide intelligence, or reveal information about a group or individual. Because the word can imply that someone is acting against former associates, it is often more emotionally charged than the more formal “informant.” In journalism, literature, and political discussion, “informer” may describe a person whose disclosures expose misconduct or threaten powerful interests. Its history also reflects the longstanding presence of spies, agents, and tipsters, although modern usage extends far beyond formal intelligence work. Understanding the word requires noticing both its literal meaning and its suggestion that information is being passed on in a way that may affect other people.

Where does informer come from?
“Informer” was formed in English by adding the suffix “-er” to “inform,” a word that comes from Latin informare, meaning “to shape” or “to instruct.” In its earlier development, “inform” could mean to give knowledge or instruction; the agent suffix gradually came to identify a person who supplies information. The word is related to “information,” “informative,” and “informal,” all of which continue the Latin root associated with informing or shaping.
How informer is actually used
“Informer” is often derogatory, especially when referring to a person who betrays confidences or informs on others. In contexts involving law enforcement or intelligence, it may be a neutral job description, although “informant” is usually preferred. British and American pronunciation differ slightly: British English commonly uses /ɪnˈfɔːmə/, while American English commonly uses /ɪnˈfɔːrmər/.
