Free phrase and phrase unit

Abstract

This article shows grammar units and free phrases, and some criteria to find the differences between them. When a set of free words (such as a long day) is compared with phrase units, such as “Long term”, we can see that the noun day and adjectives have been retained for a long period of time. These words are used alone in the free word category The part of speech possessed by the time. The vocabulary of the language has not only increased by words, but also by phrase units. The phrase unit is a part of speech that cannot be formed in speech, but it exists as a ready-made unit in the language. Words are used in certain vocabulary contexts, that is, in combination with other words. Substantive issues are often used in combination with adjectives such as important, urgent, urgent, controversial, and subtle. The syntactic valence of these verbs is different. Semantically speaking, all sentences can be divided into motivated and unmotivated. Unmotivated phrases are often described as phrase units.
