The Chinese word 烟灰缸 (yānhuīgāng, meaning "ashtray") is a logical, descriptive compound noun formed by combining three morphemes: 烟 (yān, "smoke" or "tobacco"), 灰 (huī, "ash"), and 缸 (gāng, "jar" or "vessel"). It follows a common Chinese word-formation pattern where modifiers are placed before the core noun, literally creating the meaning "smoke-ash-container"—a vessel specifically for tobacco ash, which is a perfectly transparent and functional description of the object's purpose.
