Abstract:

When seeking freelance copywriters, many buyers specify that their only interest is in writers who speak English as a native language. Frequently buyers will request writers from a particular country such as the USA, the UK, Canada or Australia. This overlooks the fact that English is spoken as a first or second language in many countries. In fact, except for Mandarin Chinese, English is the most spoken language in the world.
