Pass on information about a nobleman (7)
I believe the answer is:
recount
'pass on information' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'about a nobleman' is the wordplay.
'about' becomes 're' (regarding).
'a nobleman' becomes 'count' (count is a kind of nobleman).
're'+'count'='RECOUNT'
Can you help me to learn more?
(Other definitions for recount that I've seen before include "Go over details" , "Communicate" , "Relate" , "Give report" , "result of close-run ballot" .)
