Symbolic interactionism is a major social theory perspective that focuses on the symbolic meanings that develop through social interaction. It views humans as understanding themselves and their environment through practical, interactive experiences. The term was coined by Herbert Blumer to describe the approach of understanding human conduct and life through the symbolic meanings created between individuals. Central to this perspective are the ideas that humans act based on the meanings and interpretations they assign people and things through social interaction, language originated as a system of symbols to facilitate this interaction and thinking, and thought is modified through the interpretation of symbols.
