渥

Physical saturation (soaking, drenching, dyeing) and metaphorical abundance (great, deep, lavish, profound). When modifying terms such as 恩 (grace/favor), it indicates that the favor is lavish or abundant.

Verb: To soak, drench, or enrich. Adjective: Deep, abundant, or lavish; in high-register contexts, the abstract sense of "lavish/profound" is generally more likely than a literal reference to moisture.

Contrast with 沃: While occasionally interchangeable, 沃 typically refers to agricultural irrigation and fertility, whereas 渥 tends toward general saturation or abstract states of abundance.

The transition from physical soaking to metaphorical depth is bridged by the idea of enrichment—saturating something with a quality (such as dye or nutrient) to change its state.
