Melissa wanders, lacking purpose (7)

I believe the answer is:

aimless

'lacking purpose' is the definition.
(I've seen this before)

'melissa wanders' is the wordplay.
'wanders' indicates an anagram.
'melissa' with letters rearranged gives 'AIMLESS'.

(Other definitions for aimless that I've seen before include "Like characters in 5D {WAITING FOR GODOT]" , "Lacking ambition or target" , "Drifting - Melissa (anag)" , "Melissa (anag) -- unmotivated" , "Without direction or ambition" .)

I've seen this clue in The Times.
