In the vanguard ought you to appear valiant? (7)
I believe the answer is:
doughty
'valiant?' is the definition.
(I've seen this before)
'in the vanguard ought you to' is the wordplay.
'in' indicates a hidden word.
'DOUGHTY' can be found hidden inside 'vanguard ought you to'.
'appear' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for doughty that I've seen before include "Brave, resolute (arch.)" , "Stout-hearted, valiant" , "Fearless" .)
