The kanji 降 fundamentally means "to descend," "to come down," or "to fall." It implies a movement from a higher position to a lower one, whether it's related to physical descent, like rain falling, or metaphorical descent, such as surrendering or lowering oneself. It also encompasses the idea of something arriving or being bestowed upon someone.

・On-yomi (音読み): コウ (kō) ・Kun-yomi (訓読み): ・お降りる (o降riru) - to get off, to descend, to alight ・ふ降る (fu降ru) - to fall (of rain, snow, etc.)

⚫︎ 雨が降っている。 Translation: It's raining. ⚫︎ 階段を降りる。 Translation: To go down the stairs. ⚫︎ 幸福が降りてきた。 Translation: Happiness has descended. (or: Happiness has come upon me.)

The kanji 降 is a phono-semantic compound (形声文字). The left side is a radical (部首), 阜 (fù), which originally depicted a mound or a steep place, and later came to mean "hill" or "slope." The right side is 各 (gè), which originally conveyed the sound of "coming down." Thus, the character combined the meaning of a "slope" with the sound component to depict the action of "descending" or "falling" down a slope or a similar elevated area.
