Contextual explanation: Study of meaning-making through social signs and symbols. 
Social semiotics is best understood as the study of how individuals and groups create, communicate, interpret, and negotiate meaning using socially shared signs and symbol systems. It focuses on the dynamic processes by which meaning is constructed and understood within specific social and cultural contexts.

Themes: Cultural context and meaning negotiation. 
Social semiotics is central to the theme of meaning negotiation, as it examines how meaning is not fixed but is constantly shaped and reshaped through social interaction. It also highlights the importance of cultural context, since the interpretation of signs and symbols varies across different communities and situations.

Nuance: Socially situated interpretation. 
What distinguishes social semiotics within its category is its emphasis on the social dimension of sign interpretation. Unlike general semiotics, which may focus on abstract sign systems, social semiotics foregrounds how meaning is actively constructed, contested, and transformed through social practices and power relations.
