Flag a number of points for one of the Languages (6)
I believe the answer is:
ensign
'flag a number' is the definition.
'ensign' can be an answer for 'flag' (I've seen this before). I'm not sure about the 'a number' bit.
'points for one of the languages' is the wordplay.
'points' becomes 'en' (compass points east and north).
'for' is a charade indicator (letters next to each other).
'one of the languages' becomes 'sign' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'en'+'sign'='ENSIGN'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for ensign that I've seen before include "Small flag or junior naval officer" , "Lowly ranked officer" , "Commissioned rank in some navies" , "Flag - junior American naval officer" , "Flying" .)
