Camp male embracing a student (6)
I believe the answer is:
stalag
'camp' is the definition.
(German prison camp in World War 2)
'male embracing a student' is the wordplay.
'male' becomes 'stag' (a stag is a male deer).
'embracing' means one lot of letters goes inside another.
'student' becomes 'l' (as in L-plates for learner drivers).
'a'+'l'='al'
'stag' going around 'al' is 'STALAG'.
(Other definitions for stalag that I've seen before include "German POW camp in WWII" , "German camp for POWs" , "Water at the mouth" , "WWII German prisoner of war camp" , "German prisoner-of-war camp of WW2" .)
