Information taken to heart by Eugenie (3)
I believe the answer is:
gen
'information' is the definition.
(gen can informally mean information)
'heart by eugenie' is the wordplay.
'heart' indicates the answer is hidden within the clue (I've seen 'heart of' mean this).
'GEN' can be found hidden inside 'by eugenie'.
'taken to' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for gen that I've seen before include "Information (colloq.)" , "'Information, colloquially (3)'" , "Informal information" , "opening book, in short" , "Information yielded" .)
