words that come from the greek root chronos
Kairos as portrayed in a 16th-century fresco by Francesco Salviati. Kairos (ÎºÎ±Î¹ÏÏÏ) is an ancient Greek word meaning the right or opportune moment (the supreme moment). The ancient Greeks had two words for time, chronos and kairos. While the former refers to chronological or sequential time, the latter signifies a time lapse, a moment of indeterminate time in which everything happens.
