偶像 (ǒu xiàng) literally means 'statue' or 'image' — 偶 (ǒu) originally referred to a wooden or clay figure used in rituals, and 像 (xiàng) means 'likeness' or 'image'. Over time, the term evolved to refer metaphorically to a person admired intensely for their qualities, achievements, or charisma — much like a revered statue in a temple. It carries strong emotional weight, implying deep respect, emulation, and sometimes even devotion.

In modern usage, 偶像 most commonly describes celebrities — singers, actors, athletes, or influencers — whom fans look up to and model themselves after. Unlike the more neutral term 名人 (míng rén, 'famous person'), 偶像 implies personal identification and emotional investment. It’s frequently used by young people, especially in contexts of fandom, media, and social identity. The word can also be applied to non-celebrities — such as a respected teacher or family member — though this is less common in everyday speech.
