Bali hosts oil trade terminals - it is what it is (4)
I believe the answer is:
isle
'it is what it is' is the definition.
The definition suggests a singular noun which matches the answer.
'bali hosts oil trade terminals' is the wordplay.
'terminals' says to take the final letters (I've seen 'terminal' mean this (terminal refers to the end)).
The final letters of 'bali hosts oil trade' are 'ISLE'.
Can you help me to learn more?
(Other definitions for isle that I've seen before include "Dogs, perhaps" , "'There is an ..., a bonny ...' (rugby anthem in the South)" , "9 ac perhaps" , "Wight, Man or Skye" , "Capri for one" .)
