Can banking venture start to annoy Asian? (7)
I believe the answer is:
tibetan
'asian?' is the definition.
(Tibet is in Asia)
'can banking venture start to annoy' is the wordplay.
'can' becomes 'tin' (both are metal containers).
'banking' indicates putting letters inside.
'venture' becomes 'bet' (bet is a kind of venture).
'start to' indicates taking the first letters.
The initial letter of 'annoy' is 'a'.
'bet'+'a'='beta'
'tin' placed around 'beta' is 'TIBETAN'.
(Other definitions for tibetan that I've seen before include "Former nationality of citizen of Lhasa" , "Oriental" , "from high land" , "Asian" , "Himalayan language" .)
