Usage
What does determined mean? Determined means firmly set in one’s decision or course of action, especially with the aim of achieving a particular goal. Someone who’s determined to do something is extremely motivated and unlikely to quit or change their mind. Someone who’s determined in general has a very strong desire to achieve their goals. Someone who’s determined in this way is said to be showing determination—the quality of being firm in one’s purpose. Determined is also the past tense form of the verb determine, meaning to decide or settle in an authoritative way or conclude after observation. The term undetermined uses this sense of the word. Something that’s undetermined has not been conclusively decided or settled. (It’s not used to describe someone who’s not particularly motivated.)Example: I am absolutely determined to finish this race, even if I have to crawl across the finish line.

Etymology
Origin of determined
Explanation
Olympic athletes are some of the most determined people you're going to meet. At that level, they've got to be driven to succeed. Otherwise, their opponents will surely beat them. If you want to reach your goal, you must be determined to do so. To be determined is to be motivated, driven, or really focused on the task at hand — and that can be something as big as winning a prize or as small as fixing a squeaky door. No matter the task, the folks who get the job done are almost always the most determined. Determined can also mean "decided." For instance, a judge can determine what the sentence will be. If that sentence is predetermined, then it's already been decided.
