The word **患有 (huànyǒu)** is formed through the common Chinese morphological process of **compounding**, where two independent characters, each with their own meaning, combine to create a specific verb. The first character, **患 (huàn)**, carries the core meaning of "illness," "suffering," or "to contract (a disease)." The second character, **有 (yǒu)**, is a fundamental verb meaning "to have" or "to possess." When combined, they create a single transitive verb meaning "to suffer from" or "to be afflicted with," typically used for diseases, disorders, or medical conditions. The structure follows a logical semantic order: **患** provides the thematic domain of ailment, and **有** adds the grammatical function of possession, resulting in "to have an illness."
