Old tribesman indeed depicted (4)
I believe the answer is:
pict
'old tribesman' is the definition.
The definition suggests a singular noun which matches the answer.
'indeed depicted' is the wordplay.
'PICT' is hidden in amongst the letters.
However, I'm uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for pict that I've seen before include "N. British tribesman" , "Scotsman" , "Old Scot" , "Literary term for painted woman" , "Very old person" .)
