‘句型’ (jù xíng) literally combines 句 (jù), meaning 'sentence' or 'clause', and 型 (xíng), meaning 'type', 'form', or 'pattern'. Together, it refers to a standardized grammatical structure used repeatedly in Chinese — like the pattern for asking questions with 吗, forming comparisons with 比, or expressing result complements. These patterns are foundational in language learning because they provide reusable templates that help learners construct correct, natural-sounding sentences without memorizing every possible sentence individually.

Teachers and textbooks often introduce grammar through 句型: students practice substituting vocabulary into fixed frames (e.g., ‘Subject + 要 + Verb + 了’ for imminent future actions). Unlike isolated vocabulary, 句型 emphasizes functional usage — how words interact syntactically. Mastery of common 句型 builds fluency faster than focusing only on individual characters or words, especially for beginners navigating Chinese’s topic-prominent and aspect-rich grammar.
