Worn-out type in this puzzle, with pop-up blocker installed? (10)
I believe the answer is:
threadbare
'worn-out' is the definition.
(thesaurus)
'type in this puzzle with pop-up blocker installed?' is the wordplay.
I cannot quite understand how this works, but
'pop-up' could be 'ad' (a pop-up is a type of online advertisement) and 'ad' is found in the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for threadbare that I've seen before include "deprived of nap" , "cliche-ridden" , "Hackneyed" , "Ragged" , "Tired" .)
