Information from reduced officer (3)
I believe the answer is:
gen
I believe this is a double definition.
'information' is the first definition.
(gen can informally mean information)
'reduced officer' is the second definition.
(abbreviation for general; 'reduced' indicates a short form)
'from' is the link.
(Other definitions for gen that I've seen before include "opening book, in short" , "Informal information" , "Information (colloq.)" , "Info" , "Information yielded" .)
