Shaky persons, surely, skiing here? (7,6)
I believe the answer is:
nursery slopes
'skiing here?' is the definition.
'shaky persons surely' is the wordplay.
'shaky' indicates anagramming the letters.
'persons'+'surely'='personssurely'
'personssurely' with letters rearranged gives 'NURSERY SLOPES'.
(Other definitions for nursery slopes that I've seen before include "Areas for skiing beginners" , "Area for beginners when skiing" , "Where novices learn winter sport" , "Place for ski beginners" , "Where learners ski" .)
