About
The character 殚, with its traditional form 殫, is structured with the semantic component 歹, which commonly relates to adverse or extreme conditions, and the phonetic component 单 (simplified from 單). Etymologically, this combination conveys the notion of using something to its absolute limit, resulting in complete exhaustion. Historically, the character has denoted thorough depletion, as in classical expressions such as 殚精竭虑, referring to the expenditure of all mental and physical effort. Its core meaning of total consumption has remained focused on this sense of exhaustive extremity over time.
