Enthusiastic about Britain, totally? Only partially (4)

I believe the answer is:

into

'enthusiastic about' is the definition.
(I've seen this before)

'britain totally? only partially' is the wordplay.
'partially' indicates a hidden word.
'INTO' is hidden in the letters of 'britain totally only'.

(Other definitions for into that I've seen before include "To a position inside" , "Enthusiastic about" , "Fascinated by" , "Not I (anag.)" , "Two -- six is three" .)

I've seen this clue in The Telegraph.
