Stout fellow with a burden to bear (6)
I believe the answer is:
porter
'stout' is the definition.
(synonyms)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for porter that I've seen before include "Black beer or hotel employee" , "Dark beer; carrier" , "One fetches and carries the drink" , "Gatekeeper; beer" , "Baggage-handler" .)
