I think right about now is a good time for the world to get another Keanu, other than famous actor Keanu Reeves, and I think Key could be a very heartwarming nickname. Keanu is Hawaiian meaning "the breeze," or "cool breeze." There were 159 baby boys named Keanu in 2011. More correctly pronounced ke-AHN-oo/kay-ahn-oo, but I think the American pronunciation has taken over now.
Searching for a different Hawaiian name starting with K? Try Kai or Kekoa.
