Not obstructed, but having picnic stolen? (10)
I believe the answer is:
unhampered
'stolen?' is the definition.
Both the answer and definition are adjectives. Maybe there's an association between them I don't understand?
'not obstructed but having picnic' is the wordplay.
I cannot really see how this works, but
'not' could be 'un' (prefix meaning 'not') and 'un' is found within the answer.
The remaining letters 'hampered' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for unhampered that I've seen before include "Not weighed down" , "free" .)
