IPA: /ˈdeɪˌbreɪk/
KK: /deɪˌbreɪk/
The time in the morning when the sun starts to rise and the day begins.
We woke up early to watch the beautiful colors of daybreak.
Daybreak is formed from "day" (from Old English "dæg", meaning the period of light between sunrise and sunset) and "break" (from Old English "brecan", meaning to break or burst). The term "daybreak" refers to the moment when the light of day breaks the darkness of night.
Think of the 'day' starting to 'break' through the darkness — that's why daybreak means the beginning of the day.
