Throw away photograph (3,4,2)
I believe the answer is:
get shot of
'away photograph' is the definition.
The definition suggests a verb in its base form which matches the answer.
'throw' is the wordplay.
I cannot really understand how this works, but
'throw' could be 'shot' (shot is a kind of throw) and 'shot' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for get shot of that I've seen before include "Manage to photograph" , "ditch?" , "Eliminate" , "Kick" .)
