Girl in bar disheartened prohibitionist? (6)

I believe the answer is:

banner

I'm a little stuck... Click here to teach me more about this clue!

'prohibitionist?' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.

'girl in bar disheartened' is the wordplay.
'girl' becomes 'anne' (girl's name).
'in' is an insertion indicator.
'disheartened' says to hollow out the word (remove centre letters).
'bar' with its centre taken out is 'br'.
'anne' placed into 'br' is 'BANNER'.

Can you help me to learn more?

(Other definitions for banner that I've seen before include "Standard; heading" , "Military standard" , "Streamer, flag" , "One prohibiting - flag" , "Streamer for Clare" .)
