n. [Lat. informans, p. pr. of informare. See INFORM, v.]

  1. One who informs, or gives intelligence.
  2. One who offers an accusation. See INFORMER.

Syn. — Informer; accuser. — INFORMANT, INFORMER. These words had originally two distinct senses: 1. One who gives information in general. 2. One who points out persons for punishment. At the present time informant is applied to the first, and informer to the second case.
