Ageism in airbrushed pictures (8)
I believe the answer is:
imagines
'pictures' is the definition.
(I've seen this before)
'ageism in airbrushed' is the wordplay.
'ageism in' can be anagrammed to 'IMAGINES'.
Though, I am not sure how this is indicated.
Can you help me to learn more?
(Other definitions for imagines that I've seen before include "Formed a mental image of something not present" , "Conceives in the mind" , "Dreams of" , "Conjures up in the mind" , "Supposes" .)
