The Chinese word 加热 (jiārè), meaning "to heat", is a straightforward compound formed by combining the verb 加 (jiā), meaning "to add" or "to apply", with the noun 热 (rè), meaning "heat". This creates a verb-object grammatical structure within a single word, where the action ("to add") is directly applied to its object ("heat"). This logical and transparent formation is common in modern Chinese, efficiently conveying the concept of causing an increase in temperature by literally describing the process of "adding heat" to something.
