The Chinese idiom "熟视无睹" is formed by combining "熟视", meaning "to look at frequently" or "be accustomed to seeing", with "无睹", meaning "not to see". The character "熟" conveys familiarity, "视" means to look, "无" indicates without, and "睹" means to see. Together, they create a literal meaning of "familiar look without seeing", describing the act of ignoring something due to overfamiliarity.
