The word 传唤 is a compound formed by combining two synonymous morphemes, 传 (chuán, meaning "to transmit" or, in a legal context, "to summon") and 唤 (huàn, meaning "to call" or "to summon"). This type of word formation, where two characters with similar meanings are paired, is common in Chinese to create a precise and formal term; the semantic reinforcement intensifies and specifies the meaning, shifting from a general "calling" to the specific, official act of a legal summons issued by an authority like a court or police.
