Gave the wrong date to the fellow (7)
I believe the answer is:
donated
'gave' is the definition.
(donating is a kind of giving)
'wrong date to the fellow' is the wordplay.
'wrong' indicates anagramming the letters.
'to' means one lot of letters go next to another (I've seen this in other clues).
'the fellow' becomes 'don' (both can mean an academic).
'date' anagrammed gives 'ated'.
'ated' after 'don' is 'DONATED'.
'the' is the link.
(Other definitions for donated that I've seen before include "Given" , "Gave" , "Presented" .)
