Semantic barriers: Semantics is the branch of linguistics dealing with the meaning of words and sentence

• Technical jargon: It is usually found that specialists use technical jargon while explaining to persons who are not specialists in the concerned field. Therefore, they may not understand the actual meaning of many such words
• Faulty translations: Sometimes the communications originally drafted in one language (e.g., English) need to be translated to the language understandable to worker 

Psychological barriers: Emotional or psychological factors acts as barriers to communicators. For example, a worried person cannot communicate properly and an angry receiver cannot understand the real meaning of message. 

• Distrust: Distrust between communicator and communicate acts as a barrier. If the parties do not believe each other, they can not understand each others message in its original sense

Personal barriers: The personal factors of both sender and receiver may exert influence on effective communication

• Fear of challenge to authority: If a superior perceives that a particular communication may adversely affect his authority, he or she may withhold or suppress such communication.
