A watchable part for Mr Savalas (5)
I believe the answer is:
telly
'savalas' is the definition.
(I've seen this in another clue)
'a watchable part for mr' is the wordplay.
I cannot quite see how this works, but
'part' could be 'ell' (ell is a kind of part) and 'ell' is located in the answer.
'mr' could be 'ty' and 'ty' is found within the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for telly that I've seen before include "'The box' (colloquial)" , "One of the media" , "Television" , "TV (colloq.)" , "Set" .)
