Clean the inlet (4)
I believe the answer is:
wash
This clue could be a double definition.
'clean' is the first definition.
(washing is a kind of cleaning)
'the inlet' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
Can you help me to learn more?
(Other definitions for wash that I've seen before include "Clean oneself" , "Scrub" , "Clean; dilute coat" , "Laundry" , "shower" .)
