Little wind for walk in the park? (6)
I believe the answer is:
breeze
I believe this is a double definition.
'little wind' is the first definition.
(a breeze is a soft or gentle wind)
'walk in the park?' is the second definition.
(I've seen this before)
'for' is the link.
(Other definitions for breeze that I've seen before include "A light pleasant wind" , "Given piece of cake" , "get the wind up" , "Light wind - piece of cake!" , "little bit of wind" .)
