Termination means bringing something to an end, often in a formal or official way. When a company announces the termination of a product line, they're stopping production of those items. When someone faces termination from their job, their employment is ending, usually because they were fired rather than because they quit.

The word carries a sense of finality and authority. A teacher might end class for the day, but a school board votes on the termination of an entire program. You might stop reading a book, but a publisher decides on the termination of a book series. The word suggests a deliberate, official decision to stop something that has lasting consequences.

You'll see it used in many contexts: a lawyer might discuss contract termination, meaning when an agreement officially ends. A computer programmer talks about program termination when software stops running. A lease termination means a rental agreement has officially ended.

The verb form is terminate. When something terminates, it reaches its endpoint. The word sounds formal and sometimes cold because it's often used in official or legal situations where emotion takes a back seat to clear communication about endings.
