Going on all fours means moving on hands and knees or four legs. The antonyms for this phrase are standing up, rising, or walking upright. These words indicate the complete opposite of moving on all fours, which is standing tall and steady, using the legs for movement. Walking upright is a fundamental characteristic of humans that distinguishes us from animals. Therefore, standing up, rising, or walking upright symbolizes our unique identity as humans. When we stand tall and walk confidently, we exhibit poise, dignity, and authority. So, instead of going on all fours, let us stand up, walk, and move forward with confidence and pride.
