The word 忽略 is formed through the complementary combination of two characters, each contributing a layer of meaning to create the concept of "to ignore". The first character, 忽, originally conveys a sense of negligence or oversight, often with an implication of doing so casually or in a distracted state of mind (as suggested by its 心 "heart/mind" component). It is paired with 略, which means "to omit", "to leave out", or "to treat briefly". Thus, the compound 忽略 conceptually merges the idea of a careless, inattentive mental state (忽) with the active act of omission or simplification (略), fully encapsulating the meaning of overlooking or paying no attention to something.
