He watches over the newspaper (8)
I believe the answer is:
observer
'the newspaper' is the definition.
(I've seen this before)
'he watches over' is the wordplay.
I cannot really see how this works, but
'he' could be 'erv' and 'erv' is present in the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for observer that I've seen before include "Looker-on" , "Watcher, spectator" , "monitor" , "One watching attentively" , "organ on Sunday" .)
