Is girl taken in by naughty lad getting the boot? (9)
I believe the answer is:
dismissal
'the boot?' is the definition.
(thesaurus)
'is girl taken in by naughty lad' is the wordplay.
'girl' becomes 'miss' (term of address for an unmarried woman).
'taken in by' indicates putting letters inside.
'naughty' indicates an anagram.
'is'+'miss'='ismiss'
'lad' anagrammed gives 'dal'.
'ismiss' inserted into 'dal' is 'DISMISSAL'.
'getting' is the link.
(Other definitions for dismissal that I've seen before include "Notice" , "Process of being sent away" , "brush-off" , "job loss?" , "Rejection" .)
