‘御寒’ literally means ‘to ward off cold’ — combining 御 (yù), meaning ‘to defend against’ or ‘to repel’, and 寒 (hán), meaning ‘cold’ or ‘chill’. Together, they form a compound verb describing the act of protecting oneself from low temperatures, especially through clothing, shelter, or physiological adaptation. It is commonly used in health, daily life, and weather-related contexts.

The term often appears in discussions about winter preparation, traditional medicine, animal behavior, or textile functionality (e.g., ‘御寒功能’ — cold-resistance function). While it can be used transitively (e.g., 御寒保暖), it’s frequently paired with other verbs like ‘保暖’ (keep warm) for emphasis. It carries a slightly formal or literary tone and is rarely used in casual speech alone — more often as part of a phrase or compound expression.
