Can I use Dataview to capture definitions as I go in a note?

I’d like to capture definitions as part of my various notes and then have a central definitions page. Is this possible using Dataview? I don’t understand how to use the :: to capture a key/definition pair.

E.g. I’d like to be able to write something like “(CR = Change Request)” at the end of a line and make those definitions searchable later, building out my own dictionary/glossary page.

I did find a post here Abbreviations and Definitions in a Dataview table - Help - Obsidian Forum but I don’t really understand what this is doing (I’m still new to Dataview) - I think they’re creating a new page for each definition. I was hoping to make it simpler to capture on the fly.

Any other thoughts on building out a page of terms and definitions?
