place where roads or rails meet
A place where two or more roads or train tracks meet or cross.
用法模式：
at the junction of [road/line A] and [road/line B]

近义词

meeting point of physical structures
The place where two or more things like rivers, borders, pipes, or cables meet or join.
用法模式：
the junction of [thing A] and [thing B]
常见错误：
Learners may use "corner" instead of "junction" for rivers or borders. "Corner" is usually for sharp angles in rooms, streets, or objects, while "junction" is for places where continuous things join, like rivers, lines, or pipes.

meeting point of ideas or fields
A place or point where different types of work, study, or ideas come together and influence each other.

近义词
intersection (Very common in academic and formal writing for overlapping fields or ideas; slightly broader and more frequent than "junction" in this abstract sense.)
