Hope you can rely on (5)
I believe the answer is:
trust
This could be a double definition.
'hope you' is the first definition.
'trust' can be an answer for 'hope' (synonyms). I'm not certain of the 'you' bit.
'rely on' is the second definition.
(synonyms)
'can' acts as a 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" .)
