性 (indicating a characteristic)

• Pinyin: xìng
• Formation: Adjective/Verb + 性
• Hanzi breakdown: 性 = 忄(heart/mind) + 生 (life/birth), meaning innate nature

Meaning

性 (xìng) is a suffix added to words to indicate a characteristic, quality, or nature. It transforms adjectives, verbs, and nouns into abstract nouns describing properties or tendencies, similar to English suffixes '-ity,' '-ness,' or '-ability.'

性 is one of the most productive suffixes in modern Chinese, used extensively in formal, academic, and technical writing. Common formations include: 重要性 (importance), 可能性 (possibility), 创造性 (creativity), 安全性 (safety). It can attach to adjectives (重要 → 重要性), verbs (可能 → 可能性), and even verb-object compounds. Unlike the suffix 化 which indicates a process of change, 性 describes an inherent quality or characteristic. In formal writing, 性 words often serve as subjects or objects in analytical statements. Overuse in casual speech can sound overly academic or bureaucratic.

Examples

1. 这项技术的安全性还需要进一步验证。 The safety of this technology still needs further verification.
2. 我们必须考虑到这个方案的可行性。 We must consider the feasibility of this plan.
3. 他的发言很有针对性，直接指出了问题所在。 His remarks were very targeted, directly pointing out where the problems lie.

Do Say

Don't Say

• 今天的天气性很好。(性 cannot be added to nouns that are already concrete — 天气 is not a quality or characteristic) → 今天的天气很好。

Origin & History

性 originally meant 'nature' or 'innate character' in Classical Chinese philosophy, particularly in Confucian discussions about human nature (人性). Its modern grammatical use as a suffix creating abstract nouns developed in the late 19th and early 20th centuries, partly influenced by Japanese kanji compounds.
