About
As a phono-semantic compound, 焐 has the fire radical 火 (huǒ) on the left, linking it to heat or temperature. The right component 吾 (wú) provides the pronunciation. The character means to warm something by placing it near a heat source or using body heat to dispel cold. It describes gentle, everyday actions like warming hands at a stove, keeping an object warm under blankets, or using a hot water bottle, distinguishing it from intense burning or combustion.
