Barriers to communication can take many forms and interfere with the effective exchange of ideas. The document identifies and describes five main categories of communication barriers: physical, semantic and language, socio-psychological, organizational, and cross-cultural. Semantic barriers occur when symbolic obstacles distort the intended message, such as differences in denotation versus connotation of words across cultures or languages. Organizational barriers to change can include threats to power and influence within the organizational structure from top administrators or a climate resistant to change.
