What is Semantics?

It is not easy to describe what the word semantics means. By its very nature it makes it difficult to describe since it means that the way you say something it can easily be construed to mean something you did not intend it to. I could say, ‘I am cold.’ That could mean the temperature is uncomfortably low for me, but it also could mean that my feelings are turned off and my heart is cold. Do you get the drift?
