Teach Europeans about old Continental coin (7)
I believe the answer is:
educate
'teach' is the definition.
(educating is a kind of teaching)
'europeans about old continental coin' is the wordplay.
'europeans' becomes 'ee' (I've seen this in other clues).
'about' indicates putting letters inside.
'old continental coin' becomes 'ducat' (historical gold coin used in Europe).
'ee' placed around 'ducat' is 'EDUCATE'.
(Other definitions for educate that I've seen before include "Teach - instruct" , "Enlighten" , "Tutor" , "Inform" , "Team" .)
