Someone from an Asian country that is dismissing conclusions (4)
I believe the answer is:
thai
'asian country that is dismissing conclusions' is the definition.
'Thai' can be an answer for 'asian' (from Thailand). I am unsure of the remainder of the definition.
'someone from an' is the wordplay.
'someone' becomes 'tha' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'from' says to put letters next to each other.
'an' becomes 'i' (Roman numeral for one).
'tha'+'i'='THAI'
Can you help me to learn more?
(Other definitions for thai that I've seen before include "oriental language" , "Sort of massage" , "Citizen of the country once known as Siam" , "Native of Bangkok, say" , "Coming from Bangkok?" .)
