Celebrity photographer reads the signs? (9)
I believe the answer is:
stargazer
'reads the signs?' is the definition.
I can't tell whether this definition defines the answer.
'celebrity photographer' is the wordplay.
'celebrity' becomes 'star' (a star is a celebrity or famous person).
'photographer' becomes 'gazer' (I can't justify this - if you can you should give a lot more credence to this answer).
'star'+'gazer'='STARGAZER'
Can you help me to learn more?
(Other definitions for stargazer that I've seen before include "One looks up" , "Looker-up at night" , "Astronomer, or dreamer" , "I look at the Sun" , "Observer of the sky at night" .)
