Depot is false or assumed to be true (7)
I believe the answer is:
posited
'assumed to be true' is the definition.
I can't tell whether this defines the answer.
'depot is false' is the wordplay.
'false' is an anagram indicator.
'depot'+'is'='depotis'
'depotis' anagrammed gives 'POSITED'.
'or' is the link.
Can you help me to learn more?
(Other definitions for posited that I've seen before include "Proposed as basis for argument" , "Topside (anag.)" , "Advanced" , "Put forward as fact or as a basis for argument" , "Assumed" .)
