The antonym for the word 'more loitering' would be 'less loitering.' Loitering refers to the act of standing, waiting or staying in a public place without any apparent reason. While loitering itself is not a negative act, it can be considered a nuisance and may lead to safety concerns. Therefore, reducing the amount of loitering can have a positive impact on the community. Encouraging people to keep moving, providing more activities and opportunities for people to engage in, and enforcing the relevant laws could all contribute to reducing loitering. Ultimately, less loitering means a safer, more productive and vibrant public environment.
