Tell to check the numbers (7)
I believe the answer is:
recount
This might be a double definition.
'tell' is the first definition.
(synonyms)
'check the numbers' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
'to' is the link.
Can you help me to learn more?
(Other definitions for recount that I've seen before include "close election?" , "electoral process" , "Go over details" , "Communicate" , "possible action when votes are checked" .)
