Small typo changes in Glossary

[WillGiang]

• "benign" should have been "begin", but the sentence has been rephrased
• were -> where
• cassifies -> classifies
• removed extra spaces

Fantastic, thanks! Do you want to be acknowledged, and if so, can you list how you'd like your name displayed?

Hi @bethac07 ,

Sure, I'll suggest additional changes as well so that my contribution isn't limited to just typos!
