Radical 102 or radical field (田部) meaning "field" is number 102 out of 214 Kangxi radicals. It is one of the 23 radicals composed of 5 strokes. With 192 signs derived from this character in the Kangxi Dictionary, it has a frequency somewhat below average.
The character 田 is a pictograph of a rice field with irrigation channels. There are several variants of the radical, which may also have other meanings. Signs derived from this character mostly belong to the agricultural sphere, such as 亩, a unit of area, 男, a field worker, or 畜 "cattle".
In Chinese astrology, 申 represents the ninth Earthly Branch and corresponds to the Monkey in
the Chinese zodiac. In other signs such as 钿 "coin", the radical has merely phonetic significance. In other cases, it is present due to assimilation of a similar but originally distinct radical, as in 胃 "stomach". In the ancient Chinese cyclic character numeral system tiāngān, 甲 represents the first Celestial stem.
