Bird on lake with English name (5)
I believe the answer is:
title
'name' is the definition.
(eg the name of a book)
'bird on lake with english' is the wordplay.
'bird' becomes 'tit' (tit is a kind of bird).
'on' says to put letters next to each other (in a down clue, letters appear on others).
'lake' becomes 'L' (geographical abbreviation).
'with' is a charade indicator (letters next to each other).
'english' becomes 'E' (abbreviation as in OED).
'tit'+'l'+'e'='TITLE'
(Other definitions for title that I've seen before include "Name or designation" , "Right to possession" , "confers ownership" , "What could be professor's" , "Right - name - address" .)
