tých

Tích is a Vietnamese term of Sino-Vietnamese origin that appears as a morpheme in many words. It is not commonly used as a stand-alone verb or noun in everyday speech; rather, its meaning is determined by the Chinese character it represents and by the surrounding context. In modern Vietnamese, tích appears most often in compounds and technical terms.

There are several principal meanings tied to different Han characters. From 积/積, tích conveys notions of accumulation, storage, or gathering. Examples include tích lũy (to accumulate, accumulation) and tích tụ (to collect, to gather). In mathematics and related fields, tích denotes a product, as in tích hai số (the product of two numbers) or tích phân (the integral, calculus of accumulation). From 跡, tích can mean a trace or vestige, and appears in compounds such as kỳ tích (miracle), a term whose second character 跡 is read tích in Vietnamese.

In addition to these core senses, tích participates in numerous common phrases. Tích cực (positive, proactive) uses a Sino-Vietnamese sense of positivity, while tích hợp (to integrate, to combine) andother compound forms extend its use into technology, science, and everyday language. The exact nuance of tích in a given word is guided by the accompanying character and the broader lexical field.

Structure and usage notes: tích functions as a molding morpheme in many Vietnamese terms derived from Chinese. Its versatility reflects the broad range of concepts—accumulation, combination, and mathematical product—that Vietnamese borrows and adapts through Sino-Vietnamese vocabulary.
