Hint of rum in double in sailors’ bar (5)
I believe the answer is:
sprit
'sailors' bar' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'hint of rum in double' is the wordplay.
'hint of' indicates taking the first letters (the smallest possible amount of the word).
'in' is an insertion indicator.
'double' becomes 'spit' (as in a 'spitting image').
The initial letter of 'rum' is 'r'.
'r' inserted within 'spit' is 'SPRIT'.
'in' acts as a link.
Can you help me to learn more?
(Another definition for sprit that I've seen is " Diagonal spar extending a fore-and-aft sail".)
