Area in warmest region of SW Asia (4,4)
I believe the answer is:
near east
'sw asia' is the definition.
(I've seen this before)
'area in warmest region' is the wordplay.
'in' means one lot of letters goes inside another.
'warmest region' becomes 'nest' (nest is a kind of region. I am not sure about the 'warmest' bit.).
'area' going inside 'nest' is 'NEAR EAST'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for near east that I've seen before include "where communities are often in conflict" , "Iran and Iraq, etc" , "The Levant" , "Western Asian states formerly" , "The Balkans and Turkey" .)
