Thai people live in the outskirts of Kingston (5)
I believe the answer is:
karen
'thai people live in the outskirts of kingston' is the definition.
I can't judge whether this definition defines the answer.
'live in the outskirts of kingston' is the wordplay.
'live' becomes 'are' ('they live' means 'they are').
'in the' means one lot of letters goes inside another.
'outskirts of' suggests removing the centre (only letters on the outskirts).
'kingston' with its middle removed is 'kn'.
'are' placed into 'kn' is 'KAREN'.
Can you help me to learn more?
(Other definitions for karen that I've seen before include "Girl" , "oriental language" , "One at home in 15 across [AARHUS]" , "Carpenter of note" , "Girl's name - ethnic Thai in Burma" .)
