Dark and small Iberian chap covering face (6)
I believe the answer is:
sombre
'dark' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for sombre that I've seen before include "Dark, serious, gloomy" , "Grave or gloomy" , "Solemn and grave" , "Dark and dismal" , "Dull, gloomy" .)
