Passage this writer will read aloud (5)
I believe the answer is:
aisle
'passage' is the definition.
(aisle can mean a path or passageway)
'writer will read aloud' is the wordplay.
'writer' becomes 'I' (the person who is writing these clues).
'will' becomes ''ll' (contracted form, as in 'he'll' - 'he will').
'read aloud' indicates a 'sounds like' (homophone) clue.
'i'+'ll'='ill'
'ill' sounds like 'AISLE'.
'this' acts as a link.
(Other definitions for aisle that I've seen before include "Passageway between blocks of seats" , "Passage between seating blocks" , "Passage down the side of a church nave" , "Passage between rows of seats" , "way for prospective union members?" .)
