Germanic in origin, the meaning of the word slay means to strike or kill. In English literature, the term or related terms (slain, slew) were used to refer to ending the life of a vicious animal or enemy in battle. It conjured up images of bloodshed, and that was its full intent. Yet today, we see a very different interpretation of the same word.
A simple google search of the word slay brings up the Urban Dictionary definition as one of the first points of reference. And the new interpretation of the word now is to do something incredibly well to - kill it. This could refer to anything done with great admiration (i.e. a project/act in any field). She slayed it! She slayyyyyyyeed! Slayyyyyyy! What a difference times and seasons make. What other words are making a comeback today? I wonder what those nuances in our language say about us as a culture?
