Asian flower tax in business (8)
I believe the answer is:
industry
'business' is the definition.
(industry is a kind of business)
'asian flower tax' is the wordplay.
'asian flower' becomes 'indus' (Indian river. I am not sure about the 'asian' bit.).
'tax' becomes 'try' (I've seen this in another clue).
'indus'+'try'='INDUSTRY'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for industry that I've seen before include "The manufacture or production of goods" , "Diligence" , "Hard work" , "Commerce" , "Commercial enterprise, the making of goods, say" .)
