Articles are words that combine with a noun to indicate the degree of definiteness (specificity) of the reference being made by the noun. The articles in English are the definite article the and the indefinite articles a and an (and sometimes some). Use of the definite article implies that the speaker assumes the listener knows the identity of the noun's referent (because it is obvious, because it is common knowledge, or because it was mentioned in the same sentence or an earlier sentence). Use of an indefinite article implies that the speaker assumes the listener does not know the identity of the referent.

In English, nouns must in most cases be preceded by an article that specifies the presence or absence of definiteness of the noun. The definite article is the in all cases other than generic references, which use the zero article (i.e., the absence of an article), while indefiniteness is expressed with a or an for singular nouns or the zero article for plural or non-count nouns.

The cells in the table can be exemplified as follows:

While growing up in Santa Barbara, he often frequented the infamous Del Playa Drive, the middle of the party scene of the college town of Isla Vista, where he often found himself in fights with drunk college students.

Jennifer Shrader Lawrence (born August 15, 1990) is an American film and television actress. She had lead roles in TBS's The Bill Engvall Show and in the independent films The Burning Plain and Winter's Bone, for which she received nominations for the Academy Award, Golden Globe Award, Satellite Award, and the Screen Actors Guild Award.

Her performance in the film garnered her notable critical praise and marked her as the highest grossing action heroine of all time. Lawrence's performances thus far have prompted Rolling Stone to define her as "the most talented young actress in America."

Lawrence was born and raised in Louisville, Kentucky, and has two older brothers. Her parents are Karen (née Koch), who runs a children's camp, and Gary Lawrence, who once owned a concrete construction firm, Lawrence & Associates.

Prior to finding success in Hollywood, Lawrence attended Kammerer Middle School. She graduated from high school two years early with a 3.9 average in order to begin a career in acting. While growing up and in between acting, Lawrence served as an assistant nurse at the children's summer day camp that her mother ran.
