Understanding the Difference: Coincident vs. Coincidence

English grammar can be tricky, especially when it comes to words that sound similar but have different meanings. One such pair is "coincident" and "coincidence." These terms are often confused, leading to incorrect usage and misunderstandings. Let's explore the differences between them and learn how to use each word correctly.


The word "coincident" is an adjective used to describe two things happening at the same time or occurring together. It refers to events or situations that coincide or concur with one another without any direct or intentional connection. Essentially, it implies that two or more things are occurring simultaneously or concurrently.

For example, consider the sentence: "Our arrival at the station was coincident with the train's departure." Here, "coincident" emphasizes the fact that the arrival and the train's departure coincided or happened simultaneously.


In contrast, "coincidence" is a noun that refers to an unexpected or chance occurrence where two or more things happen together by accident, without any premeditation or purposeful connection. It suggests the absence of a causal relationship between the events.

For instance, in the sentence: "It's a remarkable coincidence that we both chose the same book for our book club," the noun "coincidence" emphasizes the surprising similarity in book choices, suggesting an accidental occurrence.

It is important to note that "coincidence" is often used to describe unexpected or unlikely events that seem to have a deeper meaning or significance. People often attribute such occurrences to fate or luck.

Using the Correct Word

To avoid confusion and miscommunication, it is essential to use the correct word in the appropriate context. Here are a few tips to help ensure accuracy:

  • Use "coincident" as an adjective when describing something happening at the same time or concurrently.
  • Use "coincidence" as a noun to refer to the chance occurrence of two or more events without a causal connection.
  • Remember that "coincident" is used to describe the relationship between things, while "coincidence" refers to the event itself.
