Originally a small line or dot above a longer line, indicating "up". The vertical line was added to distinguish the character from 二 (two). Phonosemantic compound. 田 represents the meaning and 尚 represents the sound. The contribution of the 田 (field) component to the meaning is unclear. The simplified character 当 was adapted from the cursive form of the traditional character 當. These notes explain the characters’ formation. Learn 上当 as a complete modern word rather than mechanically adding isolated character meanings.
