Hi @MariaBego56 thanks for your continued work on our glossary. These are helpful definitions to add - I've got a couple of suggestions to help make them even better

Hi @s-makin! :-)
Thank you very much for all your suggestions and ideas. They are thoughtful and to the point. I am learning a lot doing this work. So thank you again. I have agreed to all the changes suggested. I won't be able of doing any work until the week after next, when I will go through the rest of your updates and suggestions. Have a lovely week ahead. :-)

I'm glad you find them helpful, and don't worry if you don't have time currently. There's never any time pressure, just whenever you can is great. We're grateful for all your help :)

If there are other things you are looking to learn or practice, I can find or create some issues specifically tailored to your goals. Just let me know!
