No: HPFGUIDX 72772 In the OoP, Harry can see Snape's thoughts in the Pensieve. Yet Snape is never called severus but always Snivellus or Snivelly. I am not good enough in english to understand fully what that means. Is Snivellus just a surnam or is that Snape's real first name. And you have you got ideas and possible explanations about this name ??
