What does intersection mean?
An intersection is a point where two or more things cross, such as where two roads meet or where two lines cross in geometry. The word can also describe the crossing itself and, more figuratively, a shared meeting point between people, groups, activities, or ideas. In everyday conversation, it most often refers to a road junction: drivers are told to turn, stop, or continue at an intersection. In academic and cultural contexts, it may describe how different fields or communities overlap, as in an intersection between music and visual art. The term is useful because it captures both the physical idea of crossing and the broader idea of connection, exchange, and shared space. It is common in British and American English, although the preferred vocabulary for a road crossing varies somewhat by region.

Where does intersection come from?
The word comes from Latin intersectio, meaning “a cutting across” or “a place where two lines cross,” derived from intersecare, “to cut between” or “to cross.” In English, it was used in mathematical and geometrical contexts before becoming common for road junctions. Its relatives include section, from Latin sectio, and dissect, both associated with the Latin root secare, “to cut.”

How intersection is actually used
In general use, “intersection” often refers to a road junction, especially in North American English. In British English, “crossroads” and “junction” are also common, although “crossroads” can sometimes refer to an area rather than a precise point. The abstract use is common in discussions of art, education, culture, and ideas.
