To find the root word of "indefatigable," let's break it down. "Indefatigable" is an adjective that means never showing any signs of getting tired or tiring out. It is derived from the Latin word "defatigare," which means to tire out or exhaust.
To determine the root word, we need to remove the prefix "in-" from "indefatigable." The prefix "in-" in this context means "not" or "without." Once we remove the prefix, we are left with the word "defatigable." This word is not commonly used, but it does exist and means capable of being tired or fatigued.
Therefore, the root word for "indefatigable" is "defatigable," derived from the Latin word "defatigare." Note that the prefix "in-" changes the meaning of the word to its opposite, making "defatigable" mean capable of being tired, while "indefatigable" means not capable of being tired.
