Day″–star′ (–stär′), n. 1. The morning star; the star which ushers in the day.
A dark place, until the day dawn, and the day-star arise in your hearts. 2 Peter i. 19.
2. The sun, as the orb of day.
So sinks the day-star in the ocean bed,
And yet anon repairs his drooping head,
And tricks his beams, and with new-spangled ore
Flames in the forehead of the morning sky. Milton.
