'详尽' (xiáng jìn) is an adjective meaning 'exhaustive' or 'comprehensive', describing something that covers all relevant details thoroughly and leaves nothing important out. The first character 详 means 'detailed' or 'elaborate', while 尽 means 'complete' or 'to the fullest extent'; together, they emphasize completeness in detail. This word is commonly used in formal or professional contexts—especially in reports, medical documentation, academic writing, and technical instructions—where precision and thoroughness are essential.

It typically modifies nouns directly (e.g., 详尽的说明, 'a comprehensive explanation') or appears after verbs like 提供, 给出, or 包含 to stress the depth of information conveyed. Unlike colloquial alternatives such as 详细, 详尽 carries a stronger connotation of meticulous, almost exhaustive coverage—suggesting not just 'more detail' but 'all necessary detail'. It is rarely used in casual speech and never functions as a verb or adverb on its own.
