Hope you can rely on (5)
I believe the answer is:
trust
This clue might be a double definition.
'hope you' is the first definition.
'trust' can be an answer for 'hope' (synonyms). I am not sure about the 'you' bit.
'rely on' is the second definition.
(synonyms)
'can' is the link.
Can you help me to learn more?
(Other definitions for trust that I've seen before include "Faith (in a business combination?)" , "Firm belief (in someone)" , "Believe" , "Put one's faith in" , "Accept reliability of" .)
