Singer with extremely ladylike name (5)
I believe the answer is:
title
'name' is the definition.
(eg the name of a book)
'singer with extremely ladylike' is the wordplay.
'singer' becomes 'tit' (type of songbird).
'with' means one lot of letters go next to another.
'extremely' says to hollow out the word (remove centre letters) (only the extremes of the word are used).
'ladylike' with its middle removed is 'le'.
'tit'+'le'='TITLE'
(Other definitions for title that I've seen before include "'The name of a book, say (5)'" , "Proprietorship" , "Appellation of rank" , "Right of ownership" , "Name - legal right" .)
