Says it’s true about the business studies (8)
I believe the answer is:
confirms
'says it's true' is the definition.
I can't tell whether this definition defines the answer.
'about the business studies' is the wordplay.
'about' indicates putting letters inside.
'the business' becomes 'firm' (firm is a kind of business).
'studies' becomes 'cons' (to con is to study or revise).
'firm' put within 'cons' is 'CONFIRMS'.
Can you help me to learn more?
(Other definitions for confirms that I've seen before include "Corroborates" , "Provides support for the truth of" , "Provides supporting evidence of the truth" , "Supports the truth of something" , "Finalises or makes definite" .)
