窪

Denotes a topographic depression characterized by the accumulation of water. Semantic range includes:

• Topography: A hollow, dip, concave area, or "low spot."
• Feature: A basin or pit (typically larger than a simple hole but more localized than a valley).
• Ecological Result: A swamp, bog, puddle, or marshy depression.

• Noun: A landmark or feature (e.g., a hollow, a swamp).
• Stative Descriptor: Describing land as sunken or depressed.
• Verbal: Less common; may indicate the act of sinking or forming a depression.

• vs. 坑 (kēng): While both can be "pits," 坑 often implies a sharper excavation or a man-made hole, whereas 窪 suggests natural subsidence or a gentle basin.
• vs. 池 (chí): 池 refers to the body of water itself (a pond), while 窪 refers to the landform that contains it.
• vs. 沼 (zhǎo): Both can mean "swamp," but 沼 emphasizes the mud and marshy consistency of the soil/water mix, whereas 窪 emphasizes the sunken nature of the terrain.

• Fanqie reading: 烏瓜.
• Simplified variant: 洼 (U+6D3C).

The presence of the water radical (氵) is diagnostic; it specifies a site where moisture collects, seeps, or stagnates, distinguishing it from generic terms for "holes."

In a dry context, the use of this glyph likely signals a place where water would naturally gather or once existed.
