Bravery of bishop going to ancient loch (8)
I believe the answer is:
boldness
'bravery' is the definition.
(I know that boldness is a type of fearlessness)
'bishop going to ancient loch' is the wordplay.
'bishop' becomes 'B' (chess abbreviation).
'going to' is a charade indicator (letters next to each other).
'ancient' becomes 'old' (similar in meaning).
'loch' becomes 'ness' (Loch Ness in Scotland).
'b'+'old'+'ness'='BOLDNESS'
'of' acts as a link.
(Other definitions for boldness that I've seen before include "Confidence, daring" , "brass" , "Audacity" , "Courage, daring" .)
