To ignore someone or something is to pay no attention to it, on purpose or by accident. It can mean choosing not to respond, notice, or care.
From Old French "ignorer," from Latin "ignorare" meaning "not to know, not to notice." It shifted from simply not knowing to actively not paying attention.
Choosing what to ignore is as powerful as choosing what to focus on—your attention is a limited resource. Algorithms, ads, and notifications all fight to keep you from ignoring them, because your attention is literally how they survive.
