Toys, donuts, being flogged? That’s fairly good (3,2,5)
I believe the answer is:
not so dusty
'fairly good' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'toys donuts being flogged?' is the wordplay.
'being flogged?' is an anagram indicator (I've seen 'flogged' mean this).
'toys'+'donuts'='toysdonuts'
'toysdonuts' anagrammed gives 'NOT SO DUSTY'.
'that's' is the link.
Can you help me to learn more?
(Other definitions for not so dusty that I've seen before include "when the daily's been" , "Fairly well" , "It's fairly good" , "Reasonably good" , "Quite good (after housework?)" .)
