Usage: Use "decision" to refer to the final choice made after considering options or the specific act of reaching that conclusion. Avoid using it to describe the process of thinking about what to do, which should instead be called "deciding."
To defeat an opponent by a decision of the judges, rather than by a knockout

In plain English: To make a decision means to choose what you want to do after thinking about your options.

Usage: The word "decision" is not used as a verb in modern English; you must use the verb "decide" to indicate making a choice or judgment. The boxing term where a judge awards victory without a knockout refers to the noun form of the action, not a verb conjugation.
The word decision comes from the Middle French and Latin words for "cutting down" or "deciding." It entered English with its current meaning of making a choice.
