“Third Wheel” Meaning

The phrase “third wheel” refers to a person who is present in a situation or activity where two others are in a romantic relationship or close partnership, often making the third person feel like an outsider or unnecessary addition.

Origin of This Idiom

The phrase “third wheel” is derived from the phrase “fifth wheel.” “Fifth wheel” is a term that dates back to at least the 17th-century when people traveled by horse and carriage. Carriages typically had four wheels and a fifth wheel was carried aboard the carriage as a spare. This fifth wheel was considered cumbersome and often unnecessary by some. However, not all carriages at the time had four wheels. There was a two-wheel variety known as a one-horse shay. These carriages did not carry a “third wheel” but the phrase followed anyway where a spare would be thought of in the same way.

The phrase continued to be used and transferred to describing a third person in a relationship who feels uncomfortable or who makes a couple feel uncomfortable when they tag along with a couple everywhere they go.
