cielos
/ˈθjelos/ · A2 · intj
heavens!
cielos = skies, plural of cielo, from Latin caelum; cousin of celestial
Spanish speakers exclaim Cielos! the way English speakers say Heavens! or Good heavens! It is literally the plural of cielo (sky, heaven). Link it to English celestial and ceiling: same Latin root caelum, so cielos = the heavens above.
