Break small, erotic photograph (8)
I believe the answer is:
snapshot
'photograph' is the definition.
(snapshot is a kind of photograph)
'break small erotic' is the wordplay.
'break' becomes 'snap' (snapping is a kind of breaking).
'small erotic' becomes 'shot' (I can't justify this - if you can you should give a lot more credence to this answer).
'snap'+'shot'='SNAPSHOT'
Can you help me to learn more?
(Other definitions for snapshot that I've seen before include "Quick photograph" , "pic" , "Bit of camerawork" , "Informal photo" , "print" .)
