Pragmatics is concerned with the meaning, not only the lexical meaning but also it goes beyond the literal meaning to arrive at a pragmatic meaning. It needs a situation, participants and chunks of words. These words mean more than their dictionary meaning. They have some other meanings to offer. This invisible meaning is communicated through some words in a conversation. It conveys the idea of what George Yule calls "the unsaid" in his book Pragmatics and how it is kept unspoken yet communicated to other participant(s) in a shared context.
