Wash out the hair like some barber in Seville (5)
I believe the answer is:
rinse
'wash out' is the definition.
(I've seen this before)
'some barber in seville' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'RINSE' is hidden in the letters of 'barber in seville'.
'the hair like' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for rinse that I've seen before include "Wash in clean water" , "Sluice" , "Colour" , "Swill out" , "Wash without using soap" .)
