Priest possibly saw about Israeli actor (5)
I believe the answer is:
topol
'saw about israeli actor' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'priest' is the wordplay.
I cannot really understand how this works, but
'priest' could be 'p' (ecclesiastical abbreviation) and 'p' is found in the answer.
The remaining letters 'tool' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'possibly' acts as a link.
Can you help me to learn more?
(Another definition for topol that I've seen is " 'Fiddler on the Roof' star".)
