Possibly honour boy attendant identifying leaf (5,4)
I believe the answer is:
title page
'leaf' is the definition.
(title page is a kind of leaf)
'possibly honour boy attendant' is the wordplay.
I cannot really see how this works, but
'boy' could be 'page' (a young male servant) and 'page' is found within the answer.
The remaining letters 'title' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'identifying' is the link.
Can you help me to learn more?
(Other definitions for title page that I've seen before include "beginning to work" , "to start work" , "One of the first leaves" , "One starting book" , "Petite gal (anag.)" .)
