Great courage seen in survival, our own (6)
I believe the answer is:
valour
'great courage' is the definition.
'valour' can be an answer for 'courage' (valour is a kind of courage). I am not sure about the 'great' bit.
'in survival our own' is the wordplay.
'in' says the answer is hidden in the clue.
'VALOUR' can be found hidden inside 'survival our own'.
'seen' acts as a link.
Can you help me to learn more?
(Other definitions for valour that I've seen before include "Bravery, heroism" , "Great bravery" , "Bravery, especially in fighting" , "Bravery in battle" , "Courage in battle" .)
