It comes from the Latin word for equal.
"Vernal" is Latin for "spring".
aequus (equal) + nox (night)
The root word for "equinox" is Latin, with "aequus" meaning "equal" and "nox" meaning "night".
The word "equinox" comes from Latin origins, where "aequus" means equal and "nox" means night. The term refers to the two days in a year when day and night are approximately equal in length.

It means Equal Night. Equi means equal, and Nox means night. That's waht it means in Latin.
"Equinox" comes from the Latin words for equal and night, because it describes the two times each year when day and night are of equal length as the sun crosses the celestial equator.
An equinox happens twice a year, when the tilt of the Earth's axis is inclined neither towards or away from the Sun, the centre of the Sun being in the same plane as the Earth's equator. The term "equinox" is derived from the Latin "aequus" (equal) and "nox" (night). Because around the equinox, day and night have an approximately-equal length.
The sun is at the celestial equator, appearing to go Northwards at the vernal equinox and southwards at the autumnal equinox. The word equinox derives from the Latin roots for "equal" and "night" and so, not surprisingly, the night time is the same as day time: 12 hours each.
