This is kind of a silly question. I always get "regular" spaces and "normal" spaces confused in topology. This will be a problem if I am asked on a qualifier to prove something about one of these spaces. Is there any linguistic or historical justification to why a regular space deals with a point and a closed set, and a normal space deals with two closed sets?(adsbygoogle = window.adsbygoogle || []).push({});

Otherwise I'm going to need a mnemonic...
