What does con in the middle of a word mean?

"Con" in the middle of a word usually indicates "with" or "together". It comes from the Latin prefix "com", which means "with" or "together."

Here are some examples:

* Concurrent: Happening at the same time.

* Continuous: Without interruption.

* Confirm: To make certain or sure.

* Connect: To join together.

* Concentrate: To focus together.

It's important to note that while "con" is often used in this way, it can also have other meanings depending on the word. For example, in "contradict," "con" indicates "against."
