When I was a child, the song "The First Noel" had me thinking that the word "certain" could be a verb. The line "The first Noel the angels did say was to certain poor shepherds in fields where they lay" meant to me that the poor shepherds were uncertain about something, so the angels came to "certain" them, that is, to make them certain.
