What 窪 means
It means a hollow or low place that can hold water. Copy it from the palette above for that literal sense: low ground, dips, and puddles, not a feeling. Japanese uses it in 窪地 for low land and 笑窪 for a cheek dimple.
The defended dictionary record starts around 100 CE: Shuowen Jiezi records 漥 for clear water and a hollow, and glosses 窪 as a deep pool. Later Chinese use extends that low place to pooled water. 洼 is the simplified counterpart.
