Silliest place to find eggs? (7)
I believe the answer is:
inanest
'silliest' is the definition.
(I've seen this in another clue)
'place to find eggs?' is the wordplay.
'place' becomes 'nest' (I have seen 'Place of retreat' mean 'nest' so perhaps 'place' could also mean 'nest').
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'find eggs?' becomes 'ina' (I can't explain this - if you can you should believe this answer much more).
'nest' after 'ina' is 'INANEST'.
(Other definitions for inanest that I've seen before include "most senseless" , "Exhibiting minimal sense" , "Most stupid" , "Most silly" , "Most cuckoo" .)
