The word "more unalert" refers to a state of being less attentive or aware. Its antonyms can be more alert, attentive, observant, focused, aware, conscious, perceptive, vigilant, and cautious. When we become more alert, we are better able to respond to changes in our environment and can better protect ourselves against potential threats. Being attentive means that we are paying close attention to details, being observant means that we are aware of our surroundings, and being focused means that we are completely engaged in a particular task or activity. Developing these qualities can help us become better listeners, learners, and problem-solvers.
