Synonym discussion
Sense: noun/1
Daybreak, dawn, sunrise, and first light all describe the transition from night to morning, but they differ in timing and register. Daybreak and dawn are largely interchangeable for the moment the sky begins to lighten, though dawn is more common in everyday speech and has broader figurative use ('the dawn of civilization'). Sunrise is more specific — it refers to the instant the sun's edge appears above the horizon, which occurs after daybreak has already begun. First light is a slightly more literary or formal term, often used in military, travel, or outdoor-adventure contexts ('we set off at first light'). Daylight overlaps but is a wider term that covers the entire period of natural light after sunrise, not the transition itself. In practice, 'at daybreak' and 'at dawn' are the most natural choices for describing an early-morning departure, while 'sunrise' is best for describing the visual event of the sun appearing.

Etymology
Daybreak comes from Old English 'dæġ' (day) and 'brecan' (to break). The word paints a picture of daylight 'breaking through' the darkness of night — a metaphor that dates back over a thousand years. The same idea appears in related Germanic languages.
