It's clear the man is protected by company lease (8)
I believe the answer is:
coherent
'it's clear' is the definition.
(thesaurus)
'the man is protected by company lease' is the wordplay.
'the man' becomes 'he'.
'is protected by' is an insertion indicator.
'company' becomes 'co' (abbreviation).
'lease' becomes 'rent' ('rent' can be a synonym of 'lease').
'co'+'rent'='corent'
'he' placed inside 'corent' is 'COHERENT'.
(Other definitions for coherent that I've seen before include "Intelligible and lucid" , "making sense" , "Rational" , "Not rambling in speech or reason" , "Not rambling in speech or reasoning" .)
