Etymology
the word 'solstice' is a direct borrowing from latin 'solstitium', which is a compound of 'sōl' (sun) and 'stit-' (from 'sistere', meaning 'to stand still'). the term was coined in ancient astronomy to describe the observable phenomenon where the sun appears to pause at its northernmost or southernmost declination before reversing direction. this literal concept of the 'sun standing still' elegantly captures the momentary cessation in the change of the sun's noonday position at its seasonal extremes. the word entered middle english via old french, retaining its precise technical meaning related to the solar cycle.
