Holy man depressed with hovel broken (5)
I believe the answer is:
'holy man' is the definition.
(I've seen this before)
'depressed with hovel broken' is the wordplay.
I cannot really understand how this works, but
'depressed' could be 'sad' and 'sad' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sadhu that I've seen before include "Hindu wandering holy man", "Indian wandering holy man", "one choosing austerity", "Indian holy man or sage", "Ascetic".)
