Se croiser vs. se couper
In French, 'se croiser' and 'se couper' both refer to the action of intersecting or crossing each other but are used in slightly different contexts and connotations. Let's explore the differences between these terms with examples.
Se croiser
'Se croiser' means to cross each other or intersect in a way that might suggest passing by or meeting briefly. It is often used for lines, paths, or even people's routes.

Se couper
'Se couper' also means to intersect but with more emphasis on the cutting or intersecting itself. This term is often used for lines or roads where a sense of slicing through each other is implied.

Summary
