This lyric from the band Vampire Weekend asks a good question. The answer; I do. You see, commas are one of the most versatile punctuation marks. The oxford comma so detested by this “trustafarian” band is used in a list of three or more terms, after the second-to-last term, before the “and.” For example, in the phrase “red, white, and blue,” the comma after “white” is referred to as an oxford comma or a serial comma. While commas are some of the most frequently used punctuation, they are also some of the most misused. Commas should not be used to separate information that is necessary to the sentence. Consider the sentence “people who wanted to preserve wilderness area opposed the plan.” The clause who wanted to preserve wilderness areas is essential to the basic meaning of the sentence because it clarifies people and therefore should not be separated with commas.
