Originally a freelance was a knight (plus his lance) whose services were not pledged to a lord but were available for hire. The term now applies to writers and other workers who offer their services for hire. Oddly, the noun has mutated into "freelancer."
A freelancer or freelance worker is a self-employed person working in a profession or trade in which full-time employment is also common.
Fields where freelancing is especially common include journalism and other forms of writing, computer programming and graphic design, consulting, and many other professional and creative services.
But the practice is widespread: for example, bounty hunters and mercenaries are freelancers, with their full-time counterparts being, respectively, the police and the military.
