What Are Radicals?
Shén me shì bù shǒu?
什么是部首？
Radicals (部首, bùsh首) are the building blocks of Chinese characters.
Bù shǒu (bùshǒu) shì hàn zì de jī běn gòu chéng dān wèi。
部首（bùshǒu）是汉字的基本构成单位。
Each character is composed of one or more radicals—visual components that often carry meaning.
Měi ge hàn zì yóu yī ge huò duō ge bù shǒu zǔ chéng, zhè xiē shì jué chéng fèn tōng cháng yǒu hán yì。
每个汉字由一个或多个部首组成，这些视觉成分通常有含义。
Understanding radicals is like learning roots in English; it unlocks patterns and helps you guess unfamiliar characters.
Lǐ jiě bù shǒu jiù xiàng xué xí yīng wén dān cí de cí gēn; tā bāng zhù nǐ zhǎng wò guī lǜ, cāi ce bú rèn shi de zì。
理解部首就像学习英文单词的词根；它帮助你掌握规律，猜测不认识的字。

这帮助你记住相似的字在一起。
Guess new meanings – See 水 in an unfamiliar character?
