Make known or pass on (6)
I believe the answer is:
convey
I believe this clue is a double definition.
'make known' is the first definition.
(I've seen this in another clue)
'pass on' is the second definition.
(I've seen this before)
(Other definitions for convey that I've seen before include "Make known -- pass on" , "Pass on or transport" , "Transport or transmit" , "Transport; communicate" , "'Pass on, transfer (6)'" .)
