特殊 (tè shū) is an adjective meaning 'special,' 'unusual,' or 'extraordinary.' It combines two characters: 特 (tè), which conveys uniqueness or distinction, and 殊 (shū), which means 'different' or 'exceptional.' Together, they emphasize a quality that sets something apart from the ordinary—often implying rarity, significance, or deviation from the norm. Unlike colloquial terms like 特别 (tè bié), which can be used more casually for 'very' or 'especially,' 特殊 carries a more formal, objective tone and frequently appears in official, scientific, or descriptive contexts.

This word commonly modifies nouns to indicate distinctive properties—e.g., special needs, special species, or special circumstances. It’s often used in education, law, ecology, and medicine to denote categories requiring differentiated treatment. While it can describe positive traits (e.g., a special talent), it may also neutrally describe anomalies or exceptions without value judgment—such as a 特殊的动物 (a special/exceptional animal) with unique biological features.
