Expect to drink with model (7)
I believe the answer is:
suppose
'expect' is the definition.
(supposing is a kind of expecting)
'drink with model' is the wordplay.
'drink' becomes 'sup' (I've seen this before).
'with' says to put letters next to each other.
'model' becomes 'pose' ('pose' can be a synonym of 'model').
'sup'+'pose'='SUPPOSE'
'to' is the link.
(Other definitions for suppose that I've seen before include "Judge" , "Put forward - imagine" , "Fancy" , "Assume without proof" , "Think, assume" .)
