Tsui is a proper noun used as a family or given name in East Asian contexts; it can also appear in transliteration of Chinese surnames and place names. It denotes identity rather than a common lexical meaning, and is typically pronounced with a short, high-front vowel followed by a unvoiced or lightly aspirated consonantal element, depending on the original language source. Usage tends toward personal naming conventions and cultural references rather than ordinary discourse.
