The word woman can be used generally, to mean any female human, or specifically, to mean an adult female human as contrasted with girl. The word girl originally meant "young person of either sex" in English; it was only around the beginning of the 16th century that it came to mean specifically a female child. Nowadays girl sometimes is used colloquially to refer to a young or unmarried woman. During the early 1970s feminists challenged such use, and use of the word to refer to a fully grown woman may cause offence. In particular, previously common terms such as office girl are no longer used.
