Semantics studies the significance in two aspects: Diachrony and Synchrony.
Example: the word stewardess meant originally, raised of the queen, a meaning that is very different from the one that we know at the moment; what implies a diachronic change, that is, through time. The word fisco originally meant purse; very different from its current meaning.
Synchrony is the study of linguistic facts at a given moment, outside of the evolution of time, taking into account the context and meaning. This explains the meaning of a word at a given time. Example: The word fox means, literally, male of the fox; but that meaning can make reference to astute, lazy man, playing dumb, etc; this implies a synchronic use of the word.
