The antonym for the word "infinite" can be understood in terms of its meaning, which refers to something boundless, limitless, or endless. The term "finite" serves as the antonym for it, meaning something that has an end, limit, or boundary. In other words, "finite" defines something that is measurable or contains a specific quantity or number. For instance, the number of stars in the universe is infinite, while the number of planets in our solar system is finite. Similarly, the amount of energy in the universe is infinite, but the amount of fuel in your car is finite. Therefore, understanding the antonyms for the word "infinite" is crucial in differentiating between limited and boundless categories.
