The type of pronoun refers to its relationship with its corresponding words. A nominative pronoun would be "she" (i.e. She goes to the store). "She" is the subject, making it a nominative pronoun. An objective pronoun would be the object of a sentence, such as "her" (i.e. The teacher gave her a book). A possessive pronoun would be something like "my" (i.e. My car is red). In this sentence, the car belongs to me, so "my" is the possessive pronoun.
Anthropology is the study of what makes us human. Anthropologists take a broad approach to understanding the many different aspects of the human experience, which we call holism. They consider the past, through archaeology, to see how human groups lived hundreds or thousands of years ago and what was important to them.
