Picnic stroll (6)
I believe the answer is:
breeze
This clue could be a double definition.
'picnic' is the first definition.
(I've seen this before)
'stroll' is the second definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Maybe there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for breeze that I've seen before include "A light pleasant wind" , "Gust" , "Slight wind" , "Minor blow" , "The building block is light" .)
