Standard directions given with clue (6)
I believe the answer is:
ensign
'standard' is the definition.
(both can mean a flag)
'directions given with clue' is the wordplay.
'directions' becomes 'en' (east and north).
'given with' says to put letters next to each other.
'clue' becomes 'sign' (sign is a kind of clue).
'en'+'sign'='ENSIGN'
(Other definitions for ensign that I've seen before include "Lowly ranked officer" , "Flag indicating allegiance" , "Flags flown by a ship to show its nationality" , "Flag - junior American naval officer" , "officer in the US navy" .)
