Why is 'From north to south' - "Du nord au sud" but 'From left to right' is "De gauch à droite" why du versus de, why au versus à?
nord and sud are nouns
gauche and droite act as adjectives in the phrase de gauche à droite
Is this phrase used in French as it is in English? Or just a direct translation?
Why not TO left and right, eg. the cannons at the Charge of the Light Brigade?
