The English translation depends on the gender and number of the noun it precedes:
* Masculine singular: "the" (e.g., "le chat" - "the cat")
* Feminine singular: "the" (e.g., "la maison" - "the house")
* Masculine plural: "the" (e.g., "les chats" - "the cats")
* Feminine plural: "the" (e.g., "les maisons" - "the houses")
So, there's no single English translation of "le" - it always depends on the context.
