Fellow American wearing a blue checkered blazer? (8)
I believe the answer is:
flambeau
'blazer?' is the definition.
(I have seen 'Old blazer' mean 'flambeau' so perhaps 'blazer' could also mean 'flambeau')
'fellow american wearing a blue checkered' is the wordplay.
I cannot quite see how this works, but
'fellow' could be 'beau' (synonyms) and 'beau' is found within the answer.
'american' could be 'am' (abbreviation in some contexts) and 'am' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for flambeau that I've seen before include "Flaming torch" , "Torch; candlestick" , "One may be burning" , "Old blazer" , "Burning torch" .)
