Yesterday's religious leaflet or a passage from it? (7)
I believe the answer is:
extract
'a passage from it?' is the definition.
I can't tell whether this definition defines the answer.
'yesterday's religious leaflet' is the wordplay.
'yesterday's' becomes 'ex' ('yesterday's' and 'ex' can both mean former).
'religious leaflet' becomes 'tract' (I've seen this in other clues. I am not sure about the 'religious' bit.).
'ex'+'tract'='EXTRACT'
'or' is the link.
(Other definitions for extract that I've seen before include "Passage selected from a larger work" , "Remove; select (a passage) for quotation" , "Uproot by force" , "Piece taken from a longer work" , "essence" .)
