The word "she" is a third-person singular pronoun used to talk about a female. When the name of a woman has been the subject, then "she" takes the place of that name, in the text. While "she" is the subject form, the word "her" is the object or possessive form (see table below). The word "she" is used for a woman (or girl) where the word "he" would be used for a man, or "it" for a neuter pronoun.
In 1999, the American Dialect Society chose "she" as the word of the past millennium (1000-year period). The Society noted the word was not used before the year 1000; "she" was first seen in writings from the 12th century, where the word "heo" had been used to mean either the feminine or mixed plural as with "they".
