Pen directions with resolution (9)
I believe the answer is:
enclosure
'pen' is the definition.
(I've seen this before)
'directions with resolution' is the wordplay.
'directions' becomes 'en' (I've seen this in other clues).
'with' is a charade indicator (letters next to each other).
'resolution' becomes 'closure' (I've seen this in another clue).
'en'+'closure'='ENCLOSURE'
(Other definitions for enclosure that I've seen before include "Sealed-off area" , "something to accompany letter?" , "It's included, with a letter say" , "Area fenced off - one's ulcer (anag)" , "What's in the envelope" .)
