This gets the textual defs of each abbreviation from the website and translates the first "word" argument of the last path in the URL to that textual definition. I translated each of the URL's you provided. Please explain what else you need...

Shoot, Marshall, I want to replicate this interesting script, but I can't see any braces or underscores out of place. I did snip off the documentation to try to shake this error, but it remains unchanged:
