Having no direction (7)
I believe the answer is:
aimless
'having no direction' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for aimless that I've seen before include "With no plan or programme" , "Without purpose or direction" , "Drifting - Melissa (anag)" , "Lacking ambition or target" , "Without direction or ambition" .)
