solstice
/ˈsɒl.stɪs/
Definition
Either of the two times in the year, the summer solstice and the winter solstice, when the sun reaches its highest or lowest point in the sky at noon, marked by the longest and shortest days.
Etymology
The word originates from the Latin 'solstitium', which is derived from 'sol' (sun) and 'sistere' (to stand still). It reflects the ancient observation that the sun's path appears to pause or stand still at its peak or lowest point before reversing direction.
