Some drink alcohol from tap (4)
I believe the answer is:
drum
'tap' is the definition.
(I've seen this before)
'some drink alcohol' is the wordplay.
'some' says to take the initial letters.
'alcohol' becomes 'rum' (rum is a kind of alcohol).
The first letter of 'drink' is 'd'.
'd'+'rum'='DRUM'
'from' acts as a link.
(Other definitions for drum that I've seen before include "house" , "Hollow cylinder with flat ends" , "Large barrel" , "Iris rootstock (perfume)" , "Mus. instrument; container" .)
