Question

Explain when the French use the prepositions à, au, and en in front of destinations.

Answer 1

- If the destination is a city, we use the preposition 'to' before the name of the city but we sometimes use the preposition 'in' before the name of a town beginning with 'The' (Le Havre)
Ex : I go to Paris.

-If the destination is a country we use the preposition 'to' before a masculine noun, 'the' in front of a masculine plural noun but 'to' before a singular noun.
Ex: I am going to Japan.
I am going to the U.S.
I go to Germany.
I'm going to France.

Answer 2

ok, the prepositions a, au, and aux show location or direction...
ok preposition a is used before the names of cities... Je vais a paris.
en is used with feminine country names. Je vais en France.
Au is used with masculine country names. Je vais au Canada.
