Illuminating comment from a college in South American country (6)
I believe the answer is:
apercu
'illuminating comment' is the definition.
(I've seen this before)
'a college in south american country' is the wordplay.
'college' becomes 'c'.
'in' means one lot of letters goes inside another.
'south american country' becomes 'peru' (country in South America).
'c' put into 'peru' is 'percu'.
'a'+'percu'='APERCU'
'from' acts as a link.
(Other definitions for apercu that I've seen before include "Intuition" , "9 [WHATS THE POINT]" , "Brief sketch, outline" , "Glimpse" , "Precis, brief outline" .)
