'用具' (yòng jù) is a compound noun meaning 'utensil' or 'implement' — any tool or object designed for a specific practical purpose. The first character, 用 (yòng), means 'to use' or 'for use', while the second, 具 (jù), means 'tool', 'instrument', or 'item'; together, they literally convey 'an item for use'. Unlike more specific terms like 锅 (guō, 'pot') or 笔 (bǐ, 'pen'), 用具 is a general, collective term often used in formal, instructional, or descriptive contexts — for example, when listing required items for a class, workshop, or daily activity.

This word commonly appears in phrases like 日用品 (rìyòngpǐn, 'daily necessities'), 办公用具 (bàngōng yòngjù, 'office supplies'), or 厨房用具 (chúfáng yòngjù, 'kitchen utensils'). It carries a neutral-to-formal register and is rarely used in casual speech to refer to single, everyday objects (e.g., you wouldn’t say '我忘带用具了' to mean 'I forgot my pen'; you’d say '我忘带笔了'). Instead, it implies a category or set of functional tools.
