乙yǐ(yi3)

The character 乙 (yǐ) primarily represents the second position in a sequence, such as the second of the ten Heavenly Stems. It is often used in contexts like contracts to denote the second party (乙方) and can also signify a turning stroke in the formation of Chinese characters. Its versatility extends to being a symbol for the letter 'B' or the Roman numeral 'II' in various lists.

Strokes1Radical乙Frequency#11335DifficultyHard
Cultural note

乙 is part of the traditional Chinese system of time-keeping and calendrical calculations, being one of the Heavenly Stems used in astrology and traditional Chinese medicine. Its usage reflects the deep historical ties to Chinese numerology and the cosmological significance of numbers.

Memory tip

Imagine a winding path that bends around a corner—this represents the character 乙, which also looks like a bent line. The pronunciation 'yǐ' can be remembered by thinking of 'you' (the second person) taking a turn on this path. Visualize 'you' making a sharp turn to get to the second place!

AI study notes for 乙

Usage Notes

Common mistakes include confusing 乙 with other similar characters like 亻 (the person radical) or using it incorrectly in contexts where a cardinal number is required instead of an ordinal. Register-wise, it is neutral and can be used in both formal and informal settings. Pay attention to the tone 'yǐ' to avoid confusion with similar-sounding words.

HSK Study Tips

As an HSK Level 5 character, 乙 often appears alongside other terms related to contracts and legal matters. Students should focus on its application in contexts like agreements and the Heavenly Stems, which are foundational in traditional Chinese culture.

Common Mistakes

Learners often write 乙 incorrectly by confusing it with similar characters or using it when a cardinal number is needed. For example, saying '乙个' instead of '第二个' (the second one) is incorrect; use the ordinal form instead.
