Function to bring in noodle soup in liquid transfer system (6)
I believe the answer is:
siphon
'liquid transfer system' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'function to bring in noodle soup' is the wordplay.
I cannot quite see how this works, but
'soup' could be 'pho' (type of Vietnamese soup) and 'pho' is found in the answer.
'function' could be 'sin' (mathematical function) and 'sin' is present in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for siphon that I've seen before include "Tube taking fluid from higher to lower point" , "Kind of bottle for squirting, say soda" , "Soda dispenser" , "A bottle that squirts, say soda water" , "Bottle from which a liquid is forced by pressure of gas" .)
