A picture to take lightly? (5)
I believe the answer is:
photo
'a picture' is the definition.
(a photograph)
'to take lightly?' is the wordplay.
I cannot really understand how this works, but
'to' is found in the answer.
The remaining letters 'pho' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for photo that I've seen before include "Picture (abbr)" , "Snap - shot" , "Snap, picture" , "In brief, a snapshot" , "Pic (abbr)" .)
