Constructor-driver? (5)
I believe the answer is:
maker
'constructor' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for maker that I've seen before include "God Almighty" , "Producer" , "Fabricator; poet (arch.)" , "One who creates or constructs" , "Creator" .)
