Any disruption or failure in the process can create ineffective communication. Language is an obvious example; if you as a sender speak in a language the receiver doesn’t understand, the communication fails. Writing a message to a person who has difficulties reading is also ineffective communication. These are called barriers, and they are not all so obvious. For example, if you have an idea but lack confidence to speak up, that is a barrier. Body language, such as slouching in a chair so that it looks like you are bored, is also a barrier.
