In the Chinese writing system, radicals do more than help you look up characters in a dictionary. They also provide valuable clues about meaning and structure. Radical 142 is one of the 214 traditional Kangxi radicals and frequently appears in characters related to insects, small creatures, and biological life.
However, the semantic range of radical 142 extends far beyond literal insects. In modern Chinese, it also appears in scientific terms, metaphorical expressions, and everyday vocabulary.
So what exactly is radical 142? What is its origin, how is it written, and which common words contain it? This guide explains its meaning, structure, stroke order, and practical vocabulary examples to help you learn Chinese characters more logically and effectively.
What Is Radical 142 in Chinese?
Radical 142 (虫 – chóng) is the 142nd radical in the traditional Kangxi system of 214 radicals. Its original meaning refers to insects, worms, or small creeping creatures.
Archaeological evidence shows that the ancient form of 虫 was a pictograph resembling a snake with a raised head and curved body. Over time, its meaning expanded to represent insects, reptiles, and various small living organisms.
Examples:
- 蚂蚁 (mǎyǐ) – ant
- 蜜蜂 (mìfēng) – bee
- 蛇 (shé) – snake
When radical 142 appears in a Chinese character, it typically serves as the semantic component, indicating that the word is related to small creatures, insects, or biological life. The remaining part of the character often functions as the phonetic component, suggesting pronunciation. Beyond literal meanings, radical 142 is also used metaphorically in modern Chinese vocabulary.
