'not pouring into' is the definition.
I can't judge whether this defines the answer.

'can i prepared to hold it' is the wordplay.
'prepared' is an anagram indicator.
'to hold' indicates putting letters inside.
'it' becomes 'ont' (I am not sure about this - if you are sure you should believe this answer much more).
'can'+'i'='cani'
'cani' anagrammed gives 'cain'.
'cain' placed around 'ont' is 'CONTAIN'.

'the' acts as a link.

Can you help me to learn more?

(Other definitions for contain that I've seen before include "I cannot (anag) - hold back" , "keep within bounds" , "Control, restrain" , "Enclose" , "Hold within, suppress (7)" .)
