He’s out of the way in Paris flat (4)
I believe the answer is:
true
'paris flat' is the definition.
'true' can be an answer for 'flat' (thesaurus). I'm not sure about the 'paris' bit.
'he's out of the way' is the wordplay.
'out of' suggests deleting specific letters ('out of' can mean no longer having).
'way' becomes 'rue' (I have seen 'French way' mean 'rue' so perhaps 'way' could also mean 'rue').
'the' with 'he' removed is 't'.
't'+'rue'='TRUE'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for true that I've seen before include "Exact - loyal - honestly" , "Genuine; faithful" , "not showing 12 [DISHONESTY]" , "Genuine, actual" , "Agreeing with fact or reality" .)
