The Chinese word **火炉 (huǒlú)**, meaning "fireplace" or "stove," is a compound noun formed through semantic combination. It follows a common **modifier-head** structure where the first character **火 (huǒ)**, meaning "fire," describes the function or type of the second character **炉 (lú)**, meaning "furnace," "stove," or "hearth." Literally, it is a "fire-furnace"—a furnace or stove designed for or powered by fire, creating a single, coherent concept for a heating appliance. This logical, meaning-driven method of combining two independent characters to form a new word is typical in the formation of modern Chinese vocabulary.
