Beg to have food after rent laid out (7)
I believe the answer is:
entreat
'beg' is the definition.
(to entreat someone is to beg or plead)
'food after rent laid out' is the wordplay.
'food' becomes 'eat' (I've seen this in other clues).
'after' says to put letters next to each other.
'laid out' is an anagram indicator.
'rent' anagrammed gives 'entr'.
'eat' after 'entr' is 'ENTREAT'.
'to have' acts as a link.
(Other definitions for entreat that I've seen before include "Beg earnestly, implore" , "Will's pass" , "Sue" , "Beseech, implore" , "Ask (someone) earnestly" .)
