**-ity / -ness**

Pattern: `tính + [adjective or noun]`

Level: B2 (our estimate) · Register: formal

Typed without accents: tinh

*Tính* in front of a describing word or a noun names a quality, like English -ity or -ness: *tính khả thi* (feasibility), *tính minh bạch* (transparency), *tính bền vững* (sustainability), *tính cạnh tranh* (competitiveness), *tính chính xác* (accuracy). The result is a noun, so it can be raised, assessed or found lacking: *nâng cao tính minh bạch*, improve transparency.

You'll meet it in news reports, official documents and above all papers, which judge the *tính khả thi* of a plan or the *tính chính xác* of a model.

Its neighbours: *hóa*, after a word, is the process of becoming something (*hiện đại hóa*, modernising), while *tính* is the quality itself (*tính hiện đại*, modernity). *Mang tính* + quality says something has that character: *mang tính hình thức*, a mere formality. *Độ* also goes in front, but it measures how much: *độ chính xác cao*, a high level of accuracy.

On its own, *tính* is an everyday word for someone's nature or temper: *Tính anh ấy hiền lắm*, he's very gentle by nature. It's the same idea, a person's qualities.

In conversation, people use the plain adjective instead: *Kế hoạch này có khả thi không?* Is this plan feasible?
