Extract a word from a string - not easy for me!

I've spent all day trying to extract one word from a string and am totally frustrated. Here is a string -
    
str: "John and Terry went home"
    
I do not want anything after the part I want to find. Find the word "went".
    
find str "went"
    
"went home" is returned. How do I get only the word "went"?

case [] function works good!
Is there anything better??

There are several ways to achieve it depending on your usage context:
    
    
1) parse str [to "went" copy w to " "]
     ?? w
    
2) w: form fourth load str
     ?? w
    
3) w: fourth parse str none
     ?? w
    
4) pos: find str "went"
     w: copy/part pos find pos " "
     ?? w
    
Hope this helps.

Thanks Doc! I decided to use "either" function instead. I just needed to test for a word, not retrieve it this time.
