Large tear developed afterwards (5)
I believe the answer is:
later
'afterwards' is the definition.
(I know that afterwards can be written as later)
'large tear developed' is the wordplay.
'large' becomes 'L' (eg in clothes sizes).
'developed' is an anagram indicator.
'tear' with letters rearranged gives 'ater'.
'l'+'ater'='LATER'
(Other definitions for later that I've seen before include "Tardier" , "Following" , "After a given point in time" , "Afterward, subsequent" , "after an interval" .)
