Screenplay many tear up in a way (6)
I believe the answer is:
script
'screenplay' is the definition.
(I've seen this before)
'many tear up in a way' is the wordplay.
'many' becomes 'c' (C is the Roman numeral for r00).
'tear up' becomes 'rip' (I've seen this in another clue).
'in' means one lot of letters goes inside another.
'a way' becomes 'st' (abbreviation for street).
'c'+'rip'='crip'
'crip' inserted within 'st' is 'SCRIPT'.
(Other definitions for script that I've seen before include "Written form (of play etc)" , "Handwriting, play text" , "Screenplay" , "Text of play, film etc" , "Written text of play or film" .)
