With smoke rising fellow landing a sail boom (4)
I believe the answer is:
gaff
'a sail boom' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'with smoke rising fellow' is the wordplay.
'with' is a charade indicator (letters next to each other).
'smoke' becomes 'fag' (both can mean a cigarette).
'rising' says the letters should be written in reverse (going up in a down clue).
'fellow' becomes 'F' (abbreviation - of a society etc.).
'fag' backwards is 'gaf'.
'gaf' put next to 'f' is 'GAFF'.
'landing' is the link.
Can you help me to learn more?
(Other definitions for gaff that I've seen before include "Fisherman's stick with iron hook" , "House, once?" , "Landing hook - one's flat" , "Blunder" , "Pole with hook used by anglers" .)
