Recommend that you should tell (6)
I believe the answer is:
advise
This could be a double definition.
'recommend that you should' is the first definition.
'advise' can be an answer for 'recommend' (I've seen this before). I'm unsure of the remainder of the definition.
'tell' is the second definition.
(thesaurus)
Can you help me to learn more?
(Other definitions for advise that I've seen before include "Suggest, recommend" , "'Counsel, recommend (6)'" , "Inform (of situation)" , "Counsel, suggest" , "Issue warning" .)
