Bleak wind from south east (7)
I believe the answer is:
austere
'bleak' is the definition.
(I've seen this before)
'wind from south east' is the wordplay.
'wind' becomes 'auster' (I've seen this before).
'from' is a charade indicator (letters next to each other).
'south east' becomes 'e' (abbreviation. I am not sure about the 'south' bit.).
'auster'+'e'='AUSTERE'
Can you help me to learn more?
(Other definitions for austere that I've seen before include "Stern, severe" , "Abstemious and grave" , "Stern or very plain" , "Severe in manner" , "Grim - USA tree (anag)" .)
