A "complement" refers to something that completes or enhances another thing. For example, in cooking, a side dish can be a complement to the main course, making the meal more enjoyable. If you have a delicious steak, a side of mashed potatoes can complement it perfectly, adding flavor and texture to the dining experience. In language, a complement is a word or phrase that completes the meaning of a sentence. For instance, in the sentence "She is a talented musician," the phrase "a talented musician" complements the subject "She" by providing more information about her. This helps create a clearer picture of who she is.
