Hi,
I know that people can 'brush up on their French' or on 'their knowledge of something', but I was wondering if it's true that in many cases the word 'knowledge' is essential.
For instance: "I really need to brush up on my knowledge of macroeconomics." I can't imagine saying just 'brush up on my macroeconomics'. Perhaps there's a way of getting around the problem, but I'm at a loss as to how.
Thank you.
Ann225 I can't imagine saying just 'brush up on my macroeconomics'. This is OK, though it may seem a deliberate juxtaposition, for effect, of light-sounding "brush up on" and heavy-sounding "macroeconomics".
