Continue to hold contents near it (6)
I believe the answer is:
retain
'continue' is the definition.
(I know that continue is a kind of keep up)
'hold contents near it' is the wordplay.
'near it' anagrams to 'RETAIN'.
But, I am not sure how the anagram is indicated.
'to' is the link.
Can you help me to learn more?
(Other definitions for retain that I've seen before include "'Hold, keep back (6)'" , "Keep possession of" , "Continue to hold on to" , "Keep, hold on to something" , "Hold in position" .)
