wetland, marsh, (kokuji)
汢 centers on waterlogged ground: a wetland or marsh. It is a Japanese-made kokuji combining water and earth.
汢 is a kokuji (Japanese-made character) combining 氵 (water) and 土 (earth) to represent wetland or marsh.
Water 氵 beside earth 土 creates soggy ground: a wetland or marsh.
For ねた, imagine stepping into a marsh and your foot getting wet (nureta, ぬれた). The first two kana ねた cue the reading.
