Away in a southerly direction (3)
I believe the answer is:
out
'away' is the definition.
(synonyms)
'in a southerly direction' is the wordplay.
'in' indicates the answer is hidden within the clue.
'OUT' can be found hidden inside 'southerly direction'.
(Other definitions for out that I've seen before include "Mistaken; unconscious" , "Possibly caught" , "Away; into public domain" , "excluded" , "Away from home" .)
