title: Using regex to match multiple comma separated words
body: <p>I am trying to find the appropriate regex pattern that allows me to pick out whole words either starting with or ending with a comma, but leave out numbers. I've come up with <code>([\w]+,) </code> which matches the first word followed by a comma, so in something like:</p>
  
  <p>red,1,yellow,4</p>
  
  <p><strong>red,</strong> will match, but I am trying to find a solution that will match like like the following:</p>
  
  <p><strong>red,</strong> 1 <strong>,yellow,</strong> 4</p>
  
  <p>I haven't been able to find anything that can break strings up like this, but hopefully you'll be able to help! </p>
