Whenever semantics comes up, an initial response could be what do you mean by that, or are you trying to be mean? News or Views?
Ancient Greek: σημαντικός sēmantikós, significant is the study of meaning, reference, or truth. The term can be used to refer to philosophy, linguistics, and computer science.
Semantics can mean quite different things in different contexts; fields concerned with semantics are as diverse as psychology, law, lexicography, and logic. Pragmatics is an equally wide-ranging term, with applications in politics.
