Our crossword is a type one gets into (6)
I believe the answer is:
genius
'our crossword' is the definition.
I can't tell whether this defines the answer.
'type one gets into' is the wordplay.
'type' becomes 'genus' (I've seen this before).
'one gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'into' becomes 'i' (this might be a standard abbreviation which I don't know about).
'genus' placed around 'i' is 'GENIUS'.
'is a' acts as a link.
(Other definitions for genius that I've seen before include "Extraordinarily intelligent person" , "Exceptional intellectual power" , "Person of extraordinary intellectual power" , "Person of extraordinary talent" , "Maestro" .)
