Rail is sited centrally alongside a drinks dispenser (7)
I believe the answer is:
barista
'drinks dispenser' is the definition.
I know that 'drinks' relates to this answer.
'rail is sited centrally alongside a' is the wordplay.
'rail' becomes 'bar' (I've seen this in other clues).
'centrally' says to take the centre.
'alongside' says to put letters next to each other.
The central letter of 'sited' is 't'.
'bar'+'is'+'t'+'a'='BARISTA'
Can you help me to learn more?
(Other definitions for barista that I've seen before include "Coffee expert" , "coffee-shop employee" , "Arabist (anag)" , "Coffee bar worker" , "coffee-maker" .)
