coincident
Occurring at once
Coincident describes things that occur at the same time or occupy the same space.
Two events are coincident when they happen together: The firing coincided with her pregnancy—coincident timing that raised suspicions.
In geometry, coincident lines or points overlap exactly.
The word often implies the alignment is notable or potentially meaningful, though not necessarily caused by the same thing.
