Afrikaans is a daughter language of Dutch and—unlike Netherlands Dutch, Belgian Dutch and Surinamese Dutch—a separate standard language rather than a national variety. As an estimated 90 to 95% of Afrikaans vocabulary is ultimately of Dutch origin, there are few lexical differences between the two languages; however, Afrikaans has a considerably more regular morphology, grammar, and spelling. There is a degree of mutual intelligibility between the two languages, particularly in written form.
