To recreate means to give new life to something, to redo, or remake it. Say you become a billionaire and you grow tired of your mansion, try recreating your childhood home on your estate, so you can retire modestly.
To recreate literally means to create over. If the mural you painted on the outside of your home was damaged in a flood, you might want to recreate it with waterproof paint. Recreate can also mean reimagine. If you become the principal of your old high school, you could throw out the old subjects and recreate high school education as everlasting game day. Recreate can also mean to play — it gives us the word recreation.
