How to Write 炤 (zhào) — Meaning “To illuminate”

Imagine that fire (火) is "calling" (召) out light, like a torch summoning brightness into a dark room. The sound of 召 (zhào) is the same as 找 (to look for), so you can think of fire helping you find things by illuminating them.

The left radical 火 has a special form: its last stroke changes from a 捺 (downward right stroke) to a 提 (rising stroke) when placed on the left side. The right part 召 is written with a 刀 (knife) shape on top and a mouth 口 below; do not confuse the top part with 刂.

炤 (zhào) uses the phonetic component 召 and means "to illuminate." 灶 (zào) uses the component 土 (earth) and means "kitchen stove," a place for fire and earth. 灸 (jiǔ) uses 久 (long time) and refers to moxibustion, a medical treatment that uses slow, gentle heat.

炤 is not common in everyday conversation but appears in formal or literary contexts, such as the word 炤耀 (zhào yào, "to shine") or in names. It is sometimes used in classical poetry to describe light or radiance, similar to the more common character 照 (zhào).

Common words containing 炤 include: 炤耀 (zhào yào) — To shine or radiate; 炤明 (zhào míng) — Lighting; 炤亮 (zhào liàng) — To light up.
