I like this topic. BTW NepaliKeta2312312, writing "one's work and study.." is grammatically correct. I am a Physics Major though. Its usage is analogical to "his books" or "their cynical laughs". My word: arbitrage. Its meaning: Profiting in the International Exchange Rate Markets by moving large amounts of currency through different stock markets swiftly so that the small discrepancies in the exchange rates result in a gain for the "arbitragers".
