Respectful of lease always being accepted (8)
I believe the answer is:
reverent
'respectful' is the definition.
(associated in meaning)
'lease always being accepted' is the wordplay.
'lease' becomes 'rent' (synonyms).
'always' becomes 'ever' (synonyms).
'being accepted' means one lot of letters goes inside another.
'rent' enclosing 'ever' is 'REVERENT'.
'of' is the link.
(Other definitions for reverent that I've seen before include "showing much respect" , "Showing profound respect" , "Showing great respect" , "Showing deep respect" , "Respectful, deferential" .)
