This document discusses speech act theory and how language can be used to perform actions and not just describe things. It outlines locutionary, illocutionary, and perlocutionary acts. It also discusses how gender can influence language use and interpretations, with assumptions that women use more polite and affective language while men use more instrumental language. However, it argues these gender divisions are problematic and overlook how both gender use language for multiple purposes. Affiliative motives and social influences can also shape how language is used across contexts.
