Feel pride, say, after former schoolfellow returned as biographer (7)
I believe the answer is:
boswell
'biographer' is the definition.
(I've seen this before)
'feel pride say after former schoolfellow returned' is the wordplay.
'feel pride say' becomes 'swell' (I am not sure about this - if you are sure you should believe this answer much more).
'after' means one lot of letters go next to another.
'former schoolfellow' becomes 'ob' (abbreviation for old boy).
'returned' says the letters should be written in reverse.
'ob' written backwards gives 'bo'.
'swell' put after 'bo' is 'BOSWELL'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for boswell that I've seen before include "James --, biographer" , "Companion and biographer of Samuel Johnson" , "Bellows like Dr Johnson's biographer" , "Writer of Johnson's life" , "Samuel Johnson's biographer" .)
