ince the pre-Qin period, a homophonous restrictive adverb had existed in Chinese, and after the Eastern Han dynasty, it gradually came to be written as “cai (纔/才)”. As early as the Spring and Autumn period, cai was used as an inceptive aspect marker. By the Eastern Han dynasty, it had evolved into a near-past perfective marker, which became the predominant use of the temporal adverb cai during the Sui and Tang dynasties. From the Tang dynasty onward, the functions of the restrictive adverb and near-past perfective marker gradually converged. As the syntactic position of cai shifted progressively toward the right periphery of the sentence, it developed into a conjunctive adverb and subsequently a modal adverb during the Yuan and Ming dynasties. From the perspective of functional differentiation, cai in modern Chinese can be classified into five distinct uses. From the perspective of functional integration, however, with the exception of its purely temporal use, these functions share several common syntactic and semantic properties: they involve semantically posterior reference, scalar structure, and a quantity, state, or event that falls short of expectation. Pragmatically, cai generally conveys a negative evaluative implication. In low-magnitude constructions, cai indicates that a quantity or state is lower than expected, whereas in high-magnitude constructions, it indicates that an event occurs less readily or less fully than expected. A comprehensive description and analysis of the various functions of cai therefore require a clear and principled distinction between magnitude structures and subjective expectations.
