Explanation

Unlike a biplane, which has two sets of wings stacked on top of each other, a monoplane is designed to be sleeker and faster with just a single set of wings. The word monoplane combines the Greek prefix mono-, meaning "one," with the word plane to describe an airplane with a single pair of wings. When the monoplane design emerged in the early 20th century, it quickly gained popularity for its greater speed and efficiency compared to bulkier, double-winged planes. With their sleek, streamlined form, monoplanes became the go-to choice for aviation pioneers and eventually set the standard for nearly all modern aircraft designs, from fighter jets to commercial airliners.
