The Chinese term **唯有 (wéiyǒu)** is formed through the fusion of two classical Chinese characters to create a composite expression meaning "only if" or "solely when." The first character, **唯 (wéi)**, means "only" or "alone," serving as an adverb that emphasizes exclusivity or limitation. The second character, **有 (yǒu)**, is a verb meaning "to have" or "to exist." When combined, **唯有** functions as a conjunctive phrase that sets a necessary condition, essentially stating "only if there is..." or "there is only...," thereby highlighting an indispensable prerequisite or a singular option within a logical or rhetorical structure. This formation is a common pattern in classical Chinese that has been preserved in modern usage for formal or emphatic expression.
