Flag obtained from Jack, Oliver, and another guy (5,5)
I believe the answer is:
jolly roger
'flag' is the definition.
(Jolly Roger is an example)
'obtained from jack oliver and another guy' is the wordplay.
I cannot really see how this works, but
'from' could be 'o' (I've seen this in other clues) and 'o' is located in the answer.
'jack' could be 'j' (playing card abbreviation) and 'j' is found within the answer.
'another' could be 'r' (I've seen this in other clues) and 'r' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for jolly roger that I've seen before include "Pirate flag" , "In the main a fearful sight" , "Pirates' flag" , "standard for boarders?" , "standard not welcomed in the main" .)
