Third Wheel (Idiom Meaning and Use)

Ever hang out with two friends and you feel a little awkward because you aren’t engaged with them in the same ways as they are with each other? A typical way to say this is by using the phrase, “third wheel.”

The idea of a “third wheel” references transportation and movement in regards to cars or carts; you need four wheels to make it move. If you only had three wheels, it wouldn’t go very far. Therefore, when you say this little phrase in English, you’re making a metaphor.

The etymology of a “Third Wheel”

No one knows exactly how “third wheel” got its start. However, it is an American phrase created during the days of carts, carriages, and similar modes of transportation. It’s a polite and succinct way to say that an extra person amid two other people isn’t making the moment function properly.

Context; Connotation of “Third Wheel”

The person labeled as the “third wheel” doesn’t often carry a positive connotation. Not that it’s negative, although it very much can be. In general, though, it’s a way of pointing out the situation at hand without embarrassment or rudeness.

Sometimes it can be a cute way to excuse yourself from a romantic couple. In other situations, it could denote a person who insists on tagging along even though you clearly wish to be alone with another person. Therefore, in most contexts, the phrase will be in reference to a romantic couple with an extra person.
