According to Oxford Dictionaries, an entrepreneur is a person who starts his own business, usually taking on financial risk. The word originally comes from the French verb "entreprendre," which means to undertake.
In French, the word refers to the director of a musical institution, and lexicographers remain uncertain how it developed into its business-oriented sense. Here is how one uses "entrepreneur" in a sentence: "The famous entrepreneur is coming to teach a class on setting up a business." This noun has a number of derivative forms, including the adjective "entrepreneurial" and the noun "entrepreneurship," which means the actions or status associated with being an entrepreneur. Entrepreneurs in history include Bill Gates, Benjamin Franklin, Henry Ford and Madame C.J. Walker.
