That's *****. Constantly misusing a word does not change its meaning and the rules of the English language do not change. The suffixes "tion" and "age" are added to the end of verbs to make them into nouns. You can't transition to a new job any more than you can illumination a dark room. And you can't leverage a skill any more than you can breakage a window. The problem is that the people in charge of maintaining the dictionary aren't qualified to do so.
