When we are talking about semantics, we are directly referring to the meaning of what humans communicate. That is right, communication!. Semantics not only focuses on the meaning of the words (like dictionaries) but also, it focuses on the relationship between meanings, for example: the meaning of words, phrases, signs, and symbols. Also, Semantics studies both the real meaning of the expressions and their connotation or the way people understand those words, phrases, signs, and symbols.
