I don't know any other public figure who has inspired so many words in a single year.

That's what dictionaries do. They catalog words in popular use.

All words have life cycles.

Words take on many different meanings.

If words are doing their job, then their novelty will not be the most noticeable thing about them.

There are hundreds of thousands of words that aren't in any print dictionary today... because there's no space for all of them.
