Use a divine gift to find water (5)
I believe the answer is:
dowse
'water' is the definition.
The answer and definition can be both related to change as well as being verbs in their base form.
Perhaps you can see a link between them that I can't see?
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for dowse that I've seen before include "Look for water with a divining rod" , "Divine for water" , "Use rods to find water" , "Search for underground water using rod" , "Detect underground water" .)
