Leaf on the end of twig oozing (7)
I believe the answer is:
seepage
'oozing' is the definition.
(synonyms)
'leaf on the end of twig' is the wordplay.
'leaf' becomes 'page' (page is a kind of leaf).
'on' is a charade indicator (letters next to each other).
'the end of twig' becomes 'see' (I am not sure about this - if you are sure you should believe this answer much more).
'page' after 'see' is 'SEEPAGE'.
Can you help me to learn more?
(Other definitions for seepage that I've seen before include "Slow leaking flow" , "Ooze" , "liquid having soaked through" , "Slow leakage" , "problem with tank" .)
