香 = 禾 + 日. The top is grain 禾, a stalk of millet or rice bent under the weight of its own ripe ear. Beneath it sits what is now written 日 (sun) but was originally 甘 (gān), sweetness: a mouth with a stroke marking something held on the tongue. Put the two together and you have the literal scene the character draws, the sweet smell rising off cooked or ripening grain.

The seal form keeps the picture honest. Grain above, the sweet mouth below, with no sun in it at all. The 甘 component flattened and squared over the centuries until scribes wrote it as the simpler 日, which is why the modern glyph looks like grain over a sun. The original logic was about taste, not daylight.

From that one cooking-pot image the meaning fanned out the way an aroma does. First fragrant, the smell of anything pleasant: flowers, perfume, fresh bread. Then delicious, since a good smell promises a good taste, so 吃得很香 means eating with real appetite. Then the burnt offering, an incense stick whose smoke carries scent upward to the ancestors. And finally, by metaphor, popular or well-liked, a person or thing everyone wants, as in 吃香 (chīxiāng), to be in demand.

香 is its own radical, heading the small family of scent characters such as 馨 (xīn, lingering fragrance). In Japanese it reads ka or kō and names both perfume and the incense ceremony 香道 (kōdō); in Korean it is hyang, the scent burned at the family rite.

香 sits at the head of words for everything that smells or tastes good. As a standalone adjective it covers both senses at once: 这个菜很香 can mean the dish smells wonderful and that it is delicious to eat. Pair it with 甜 for the warm, mellow note of ripe fruit and cooked rice.

Picture the moment that built the character. A stalk of ripe grain 禾, heavy and golden, is laid across the top of a steaming clay pot. Below it a mouth holds a single grain of rice and finds it 甘, sweet. The two stacked together are the whole word: the warm, sweet smell rising off cooked rice. Read 香 top to bottom and you are reading that scene, grain over sweetness.

Hold that rising smoke in mind and every sense follows it. The same fragrant column is the incense stick at the altar in 烧香, the bottled scent in 香水, the curl off a cigarette in 香烟. Let the steam carry your appetite and you reach 香甜, the food so good you sleep soundly after it.

One last turn. When a smell is this good, everyone leans toward it. That is 吃香, to be wanted, the aroma a crowd cannot resist. Grain over a sweet mouth, scent rising, a room full of people who all want a taste.
