... while shelter may also be a man (3)
I believe the answer is:
lee
'while shelter' is the definition.
'lee' can be an answer for 'shelter' (as in lee side, the side sheltered from wind). I'm unsure of the 'while' bit.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for lee that I've seen before include "Commander of the Confederate States Army in the American Civil War" , "Revolutionary general" , "Sheltered accommodation" , "Cork river" , "Sheltered from the wind in Cork, perhaps" .)
