Hold it for the photographer (4)
I believe the answer is:
pose
'hold' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'it for the photographer' is the wordplay.
'it' becomes 'e' ('e' can mean 'electronic' which is similar to 'IT').
'for' says to put letters next to each other (I've seen this in other clues).
'the photographer' becomes 'pos' (I can't justify this - if you can you should give a lot more credence to this answer).
'e' put after 'pos' is 'POSE'.
Can you help me to learn more?
(Other definitions for pose that I've seen before include "Pretend to be somebody else" , "Pretend; model" , "Sit; attitude" , "Assume an attitude (for photo etc)" , "Model - ask (question)" .)
