Infuse, introduce (6)
I believe the answer is:
instil
I believe this clue is a double definition.
'infuse' is the first definition.
(I've seen this in another clue)
'introduce' is the second definition.
(I know that instil is a more specific form of the action introduce)
(Other definitions for instil that I've seen before include "It's nil (anag.)" , "Introduce gradually into mind, say ideas" , "Mentally fix" , "Implant (in the mind)" , "Gradually establish (in someone's mind)" .)
