暑

Atmospheric or seasonal heat, specifically the oppressive heat of midsummer and associated climatic conditions.

Primarily used as a noun ("the summer heat") or an adjective describing weather and seasonal conditions. It is rarely used as a verb.

Unlike 热 (rè), which serves as a general term for temperature (such as a fever or a hot object), 暑 is restricted to climatic conditions. In medical contexts, it often refers to the physiological affliction caused by summer heat, such as heatstroke or exhaustion.

Reading evolution toward shǔ. Fanqie: 舒吕; Tang-period reading: shiǔ.

Composed of 日 (sun) as the semantic component and 者 as the phonetic component.
