Modest offering from overseas university: English (4)
I believe the answer is:
mite
'modest offering' is the definition.
(a mite is a small amount)
'overseas university english' is the wordplay.
'overseas university' becomes 'MIT' (Massachusetts Institute of Technology).
'english' becomes 'E' (abbreviation).
'mit'+'e'='MITE'
'from' is the link.
(Other definitions for mite that I've seen before include "Tiny arachnid, person or amount of money" , "The Biblical widow's offering" , "Very small creature or child" , "Microscopic animal" , "Minute arachnid" .)
