For example blow up pub – maybe saloon bar walls ... (5)
I believe the answer is:
photo
'bar walls' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'for example blow up pub maybe saloon' is the wordplay.
I cannot quite see how this works, but
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is found within the answer.
'pub' could be 'ph' (abbreviation) and 'ph' is present in the answer.
A single letter 'o' remains which might be clued in a way I don't understand.
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 "In brief, a snapshot" , "Snap, pic" , "Snap - shot" , "Picture (abbr)" , "Snap (abbrev.)" .)
