1. Cooperation and implicature

1.4. Types of Implicature

Conversational implicature : In this case the speaker communicates meaning via implicature and the listener recognizes communicated meaning via inference.

Generalized conversational implicature: In this type, no special knowledge is required in the context to calculate the additional conveyed meaning.

Scalar implicature : There are words that are mentioned to communicate an amount of something in a scale. 

Particularized conversational implicatures : In this type,  context helps inferences to be assumed. 

Conventional implicatures:  Conventional implicatures are associated with specific words and result in additional conveyed meanings when those are used.
