The girl has the little brother carrying the flag (6)
I believe the answer is:
banner
'flag' is the definition.
(banner is a kind of flag)
'the girl has the little brother carrying' is the wordplay.
'the girl has' becomes 'anne' (I can't justify this - if you can you should give a lot more credence to this answer).
'the little' means to remove the last letter (the word is not quite complete).
'brother' becomes 'bro' (short for brother).
'carrying' indicates putting letters inside.
'bro' with its final letter taken off is 'br'.
'anne' inserted inside 'br' is 'BANNER'.
'the' is the link.
Can you help me to learn more?
(Other definitions for banner that I've seen before include "Website advertisement" , "Standard; heading" , "Knight's standard" , "Standard carried at demo etc" , "One not allowing" .)
