Learn the Language of Business

With over 20,000 definitions, the Business Dictionary covers every aspect of the business world. Seems to be especially investment- and financial-oriented. It is brought to us by WebFinance Inc., creators of InvestorGuide.com, InvestorWords.com and WiserAdvisor.com (more research resources).

Business Dictionary is a place to look up words and to learn. The website has a multitude of methods and indices with which to search. Business writing can be among the most lucrative fields for a freelancer. I highly recommend it for an area in which to specialize--and that's how to succeed as a freelancer these days.
