Hall partner (5)
I believe the answer is:
oates
'hall partner' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for oates that I've seen before include "Antarctic explorer" , "Captain -, polar explorer with Scott" , "Self-sacrificing member of Scott's Antarctic team" , "Very gallant gentleman" , "Captain on Scott expedition who died in blizzard" .)
