entrepreneur

Borrowed from French entrepreneur, meaning 'one who undertakes or manages,' from Middle French entrepreneur, itself from entreprendre ('to undertake') plus the agent suffix -eur.

The facts here don't show a shift in meaning — the word arrived in English already carrying its French sense of someone who takes on and manages a venture.

It shares its root with entreprendre, the French verb 'to undertake,' which gave the word its very core meaning.
