Distant one I set out for? (11)
I believe the answer is:
destination
'out for?' is the definition.
The definition suggests a singular noun which matches the answer.
'distant one i set' is the wordplay.
'set' indicates anagramming the letters (instruction to set the letters).
'distant'+'one'+'i'='distantonei'
'distantonei' anagrammed gives 'DESTINATION'.
(Other definitions for destination that I've seen before include "Place to which one is travelling" , "Final goal" , "End of journey" , "Journey's end" , "Where one is going" .)
