Subject of childish stories? (5)
I believe the answer is:
fairy
'subject of childish stories?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'subject of' is the wordplay.
I cannot quite understand how this works, but
'subject' could be 'ai' (AI is an example) and 'ai' is located in the answer.
The remaining letters 'fry' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for fairy that I've seen before include "Mythical being" , "Tinker Bell was one" , "Eg, Tinkerbell" , "Creature of folklore" , "Cobweb, perhaps" .)
