Live with a warm-hearted Oriental (3)
I believe the answer is:
are
'live' is the definition.
(both can mean exist)
'with a warm-hearted oriental' is the wordplay.
'with' means one lot of letters go next to another.
'hearted' says to take the centre.
'oriental' becomes 'e'.
The middle of 'warm' is 'ar'.
'ar'+'e' is 'ARE'.
(Other definitions for are that I've seen before include "live" , "(We/they/you) exist" , "Exist; square measure" , "(We/you/they) exist" , "Era (anag.)" .)
