Information on the German male or female (6)
I believe the answer is:
gender
'male or female' is the definition.
(I've seen this before)
'information on the german' is the wordplay.
'information' becomes 'gen' (gen is a kind of information**).
'on' means one lot of letters go next to another.
'the german' becomes 'der' ('the' in German).
'gen'+'der'='GENDER'
(Other definitions for gender that I've seen before include "Man or woman" , "Male or female state" , "Sex category" , "What divides males and females" , "Class such as female or male" .)
