Barrel tipped over English sailors in pub (6)
I believe the answer is:
tavern
'pub' is the definition.
(I've seen this in another clue)
'barrel tipped over english sailors' is the wordplay.
'barrel' becomes 'vat' (I've seen this before).
'tipped over' says the letters should be written in reverse.
'english' becomes 'e' (abbreviation).
'sailors' becomes 'RN' (abbreviation for Royal Navy).
'vat' back-to-front is 'tav'.
'tav'+'e'+'rn'='TAVERN'
'in' acts as a link.
(Other definitions for tavern that I've seen before include "Watering hole" , "Building with a bar" , "Alehouse" , "An old English pub" , "Local" .)
