Asian people left area with nothing (3)
I believe the answer is:
lao
'asian people' is the definition.
(I've seen this in another clue)
'left area with nothing' is the wordplay.
'left' is a reversal indicator.
'area' becomes 'al' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'with' says to put letters next to each other.
'nothing' becomes 'O' (O resembles 0).
'al' reversed gives 'la'.
'la'+'o'='LAO'
Can you help me to learn more?
(Other definitions for lao that I've seen before include "Asian" , "Indo-Chinese language" .)
