1. Definition + Rich Everyday Explanation
Intersection (noun) = a point where two or more things cross or meet, whether roads, ideas, fields, or identities.
“Intersection” is fundamentally about crossing points — places where separate things meet, overlap, or come together. The word works beautifully across physical, intellectual, and social contexts.
The most concrete meaning is where roads meet. An intersection is the point where two or more streets cross each other. This is everyday vocabulary — traffic lights are at intersections, accidents happen at intersections, you turn left at the intersection. In American English, “intersection” is the standard term; British English often uses “junction” or “crossroads,” though “intersection” is understood everywhere.
But the word extends far beyond roads into abstract territory. When two fields, ideas, or interests overlap, that’s an intersection. “The intersection of technology and healthcare” describes where these areas meet and influence each other. “The intersection of art and science” captures how these disciplines can combine. This usage is everywhere in academic, professional, and creative discussions.
In recent years, “intersection” has gained powerful meaning in social discussions. “Intersectionality” — a term from critical theory — describes how different aspects of identity (race, gender, class, disability) overlap and create unique experiences. Someone might face challenges at the intersection of being a woman and being from a minority background. This usage has entered mainstream conversation and appears constantly in discussions about equality and identity.
In mathematics, an intersection is where two sets share common elements — a precise technical meaning that echoes the broader concept of overlap.
Examples from the street:
- “Turn right at the next intersection” → turn right where the roads cross
- “Her work sits at the intersection of psychology and economics” → her research combines and connects both fields
- “People living at the intersection of poverty and disability face unique challenges” → those experiencing both conditions encounter specific difficulties
2. Most Common Patterns
- at the intersection (of two roads) → at the point where streets meet
- at / the intersection of X and Y → where two fields, ideas, or identities meet
- busy / dangerous intersection → a road crossing with heavy traffic or risks
- work / operate / exist at the intersection of → function where multiple areas overlap
- find the intersection (between) → identify where things connect or overlap
- intersectionality → the concept of overlapping identities and their combined effects
3. Phrasal Verbs
Note: There are no common phrasal verbs directly containing “intersection” — these are related expressions used in similar contexts:
- cross over (into) → move from one area or field into another
Example: “Her research crosses over into philosophy as well as science.”
- overlap with → share common elements with something else
Example: “My interests overlap with hers in several areas.”
- tie in (with) → connect or relate to something else
Example: “This idea ties in with what we discussed earlier about technology.”
