The Chinese word 叫喊 (jiàohǎn) is a compound formed by combining two synonymous characters, each carrying the core meaning of "to shout." The first character, 叫 (jiào), primarily means "to call" or "to shout," while the second, 喊 (hǎn), explicitly means "to yell" or "to cry out." This type of formation is known as a **synonym compound**, where two words of similar meaning are joined to create a single, more emphatic or comprehensive term. Therefore, 叫喊 conveys a stronger, more vivid sense of "shouting" or "bellowing" than either character would alone.
