解析 (jiě xī) is a formal verb meaning 'to interpret' or 'to parse' — especially when breaking down something complex into its constituent parts for understanding. The first character 解 (jiě) means 'to untie', 'to dissolve', or 'to explain'; the second character 析 (xī) means 'to separate', 'to analyze', or 'to examine closely'. Together, they convey the idea of carefully disassembling and explaining a structure — whether it's a sentence, a mathematical problem, a computer program, or a scientific phenomenon.

This word is commonly used in academic, technical, and professional contexts: linguistics (e.g., parsing grammar), computer science (e.g., parsing code syntax), mathematics (e.g., analyzing functions), and data science (e.g., interpreting datasets). It carries a tone of precision and intellectual rigor, and is rarely used in casual speech. While 解 alone can mean 'to understand' or 'to solve', adding 析 emphasizes methodical, step-by-step examination rather than intuitive comprehension.
