Jolly Roger, for example (4)
I believe the answer is:
flag
'jolly roger for example' is the definition.
(jolly roger is a kind of flag)
This is the entire clue.
(Other definitions for flag that I've seen before include "Emblematic rectangular piece of fabric" , "Iris -- become weary" , "Paving stone; iris; tire" , "Colours - become tired" , "Symbol or emblem of a country" .)
