Salty puffs filling for Sue having gone on a picnic (3,6)
I believe the answer is:
sea breeze
'salty puffs filling for sue' is the definition.
I can't judge whether this defines the answer.
'having gone on a picnic' is the wordplay.
'having gone' becomes 'sea' (I can't justify this - if you can you should give a lot more credence to this answer).
'on' says to put letters next to each other (in a down clue, letters appear on others).
'a picnic' becomes 'breeze' (both can mean something easy).
'sea'+'breeze'='SEA-BREEZE'
Can you help me to learn more?
(Other definitions for sea breeze that I've seen before include "Gentle wind from the ocean" , "Gentle coastal wind" , "Doctor" , "that creates a cool ambience around 6 [ISLE] ?" , "Maritime wind" .)
