Regex to match whole words that begin with $

Question

I need a regex to match whole words that begin with $. What is the expression, and how can it be tested?

Example:

This $word and $this should

Answer 1

This should be self-explanatory:

\$\p{Alphabetic}[\p{Alphabetic}\p{Dash}\p{Quotation_Mark}]*(?

Notice it doesn’t try to match digits or underscores are other silly things that words don’t have in them.
