But actually it's larger than a hutch! (3)
I believe the answer is:
hut
'hutch' is the definition.
(I know that hutch can be written as hut)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hut that I've seen before include "Small crude shelter" , "Small roughly-made house or shelter" , "Small, simple shelter" , "Small building or shelter" , "Simple house or shelter" .)
