Note you rely on completely (5)
I believe the answer is:
clean
'completely' is the definition.
(I've seen this before)
'note you rely' is the wordplay.
I cannot quite understand how this works, but
'note' could be 'n' (abbreviation) and 'n' is found in the answer.
The remaining letters 'clea' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'on' is the link.
Can you help me to learn more?
(Other definitions for clean that I've seen before include "Complete" , "Spotless; launder" , "thoroughly" , "Untainted" , "remove filth" .)
