"Demonstrative" refers to a type of communication that shows or illustrates something clearly. It often involves using gestures, expressions, or specific words to convey meaning. For example, in language, demonstrative pronouns like this, that, these, and those help specify particular items or people in a conversation. In psychology, "demonstrative" can describe behaviors that express emotions openly. People who are demonstrative may show affection through hugs or smiles, making their feelings evident to others. This openness can enhance relationships by fostering understanding and connection among individuals.
