I believe the answer is:

beacon

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

'warner' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I don't see?

'bros' first canoe up the creek' is the wordplay.
'bros' first' becomes 'b' (1st letter of 'bros').
'up the creek' indicates anagramming the letters.
'canoe' with letters rearranged gives 'eacon'.
'b'+'eacon'='BEACON'

Can you help me to learn more?

(Other definitions for beacon that I've seen before include "Warning light on a high point" , "Warning light on tower or hill" , "Warning or guiding device" , "Raised signal fire or light" , "Watch fire" .)
