"Most conjugated" refers to a word that has the highest number of different forms based on tense, mood, person, and number. Some antonyms for this word could be "least inflected," which would refer to a word that has only one or few forms, or "simple," which would suggest a lack of complexity in verb conjugation. Another antonym could be "unconjugated," which would describe a word that does not change form based on tense, mood, person, or number, such as the English word "love." In language learning, it is important to understand the various forms of a word, but having an antonym can also be helpful in distinguishing between different concepts.
