Feeder to university in western complex
I believe the answer is:
wet nurse
'feeder' is the definition.
(I've seen this before)
'university in western complex' is the wordplay.
'university' becomes 'u'.
'in' indicates putting letters inside.
'complex' is an anagram indicator.
'western' with letters rearranged gives 'wetnrse'.
'u' placed within 'wetnrse' is 'WET-NURSE'.
'to' acts as a link.
(Other definitions for wet nurse that I've seen before include "Milk supplier" , "Woman feeding another's baby" , "feeder" , "someone else to feed baby" , "Woman to help mum" .)
