Take on glossary action

Hi all,

We are looking for a volunteer who can spend some time on getting the BP glossary into shape. Peter Parslow was going to take this on, but ran out of time. Please let us know if you have some time in the coming days and are willing to help us!

To be done:
- general review, remove the yellow highlight, check definitions & amend as necessary ...
- GitHub Issues 212[1] and 39[2]
