English: At the front. At the back.
French: À l'avant. À l'arrière.
When you're asked "où est la toilette?" "where is the washroom?" you can point and respond "à l'avant" (at the front) or "à l'arrière" (at the back).
If you want to respond using a complete sentence, "the washroom is at the front/at the back" you can say "la toilette est à l'avant/à l'arrière."
As we've learned before, you can also add "on the left/right." For example, "à l'avant, à gauche" or "à l'arrière, à droite."
