Implicature refers to what a speaker implies rather than literally says. There are two main types: conversational implicature which is derived from cooperative conversation principles, and conventional implicature which is associated with specific words. Conversational implicature includes generalized implicature which does not depend on context, and particularized implicature which does. Scalar implicature also falls under conversational implicature and is implied when a weaker term on a scale is used. Particularized implicature provides more contextual information than generalized implicature. Implicatures can intentionally or unintentionally impact understanding in conversations.
