气 qì

Breath, energy, weather, temper — the single syllable that runs through everything.

The short answer

Qi (often written chi) is breath, energy, vital force — the stuff that flows through bodies, weather, food, and feelings. It is at once a medical concept, a martial-arts skill, and an ordinary syllable in words you already know.

Literal: vapor, breath, air, energyRegister: From temple to kitchen table. Fully ordinary vocabulary.

What it means

Start with the weather: 天气, sky-qi. Add a person's temper: 生气, to generate qi at someone. A student's spirit: 志气. The rice that fills you:力气 comes from eating. Chinese treats all of these as one family — gradients of the same basic stuff, moving and condensing.

In that picture, health is good circulation: Chinese medicine diagnoses blockages and drafts of qi, and practices like taiji and qigong are literally “qi work”. Whatever one believes about the metaphysics, the vocabulary is inescapable — you cannot describe feeling unwell, furious, or lucky without it.

How people use it

Everyday compounds make the concept concrete: 力气 (strength), 气色 (complexion — the qi showing in your face), 元气 (vital qi; 元气满满 means bursting with life), 气质 (temperament — the aura someone carries), and my favorite: 服气, to swallow your objection and admit someone is better.

In martial-arts and wellness contexts, qi keeps its mystical flavor — the focus, the breath control, the alleged powers. In daily speech it is as mundane as “energy” is in English.

Where it comes from

The character draws vapor rising — steam from cooking rice is the usual gloss. Philosophers made it a cosmology: qi is what the world and everything in it condenses from, and death is simply dispersal back into vapor.

From that idea grow Chinese medicine, calligraphy theory (a stroke is alive when its qi flows), feng shui (arranging rooms so qi moves well — see feng shui), and two thousand years of arguments about what, exactly, is flowing.
