Not bound to negotiate lease blockhead is holding up (5-4)
I believe the answer is:
loose-leaf
'not bound' is the definition.
(I've seen this before)
'negotiate lease blockhead is holding up' is the wordplay.
I cannot really understand how this works, but
an anagram of 'lease' is 'selea' which is located in the answer.
The remaining letters 'loof' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for loose-leaf that I've seen before include "(Of a folder) with removable sheets" , "With pages that can be easily rearranged" , "Describes binder with allows addition and removal of pages" , "Allowing the insertion and removal of pages" , "Like some folders" .)
