co-occurrence
Showing up jointly
Co-occurrence is the appearance of two or more things together, especially in a pattern that may suggest relationship.
The term appears most often in linguistics and data science, where analyzing which words appear near each other reveals meaning and usage: The co-occurrence of "strong" and "coffee" is more common than "powerful" and "coffee".
In medicine, co-occurrence describes conditions that tend to appear together in the same patient.
