Tear back again as it's more fully matured (5)
I believe the answer is:
riper
'it's more fully matured' is the definition.
I can't judge whether this defines the answer.
'tear back again' is the wordplay.
'tear' becomes 'rip' (ripping is a kind of tearing).
'back' shows that the letters should be reversed in order.
'again' becomes 're'.
're' written backwards gives 'er'.
'rip'+'er'='RIPER'
'as' is the link.
Can you help me to learn more?
(Other definitions for riper that I've seen before include "On the way to getting mellow" , "More prepared" , "like a better mousetrap?" , "More mature and ready to be eaten" , "More suitable for picking" .)
