6 year old creates a new word – Levidrome

Six year old Levi started imagining words backwards. He asked his parents if there is a word for spelling another word backwards.  When no word existed, he invented one and called it levidrome.  He proposed his word to Merriam-Webster, but to be included it has to be commonly used.  Celebs like William Shatner have joined in to help by tweeting it publicly.
