Passage Two
Sioux names were a language unto themselves, laden with descriptive, allusive, or even magical meaning. A Sioux baby was named soon after birth--usually by a medicine man or a paternal relative--and the entire village participated in the occasion. The infant might be named for an animal, for a physical phenomenon such as thunder that occurred on the day of the birth, or even for a brave deed that once had been performed by the giver of the name. A woman generally kept the name she received at birth, but a man often replace his original name with a new one that celebrated a personal act of valor, recalled an encounter with an unusual animal, or perhaps was inspired by a dream. However, a man who had a distinguishing characteristic was forever known by an apposite nickname, such as Big Hand. Because Sioux names almost always were based on something objective, they could easily be rendered as pictographs-frequently with a line connecting visual representations of the name and a human head to signify ownership. Below are some Sioux signatures.

A:an inspiring dream B:a new home C:an encounter with a strange beast D:a valiant deed
