The Chinese word **低温** (dīwēn), meaning "low temperature," is a straightforward compound formed by combining two characters: **低** (dī), which means "low" or "to lower," and **温** (wēn), which means "warmth" or "temperature." This follows the common grammatical structure in Mandarin where a descriptive adjective (低) is placed directly before a noun (温) to create a new noun phrase that specifies a type or state—in this case, a state of temperature that is low. Thus, the formation is purely semantic and syntactic, logically merging the concepts of "low" and "temperature" to express a single, clear idea.
