The antonyms for the word "more crouched" are "upright," "straight," and "erect." These words denote an upright posture, where the body is not bent or hunched over. Being upright connotes confidence, poise, and dignity. Conversely, being crouched connotes timidity, submissiveness, and vulnerability. Therefore, choosing the right word to describe one's physical posture can have a significant impact on how they are perceived by others. In situations that require authority, such as a workplace or a classroom, it is important to maintain an upright posture to convey confidence and command. On the other hand, crouching may be necessary in situations that require agility, such as sports or combat.
