le or Un
In French, adjectives and articles must agree in gender (masculine or feminine) and number (singular or plural) with the noun they modify. This means that the ending of the word may change to match the noun's gender. For example, "petit" becomes "petite" for feminine nouns. Verbs may also change according to the gender of the subject in some tenses.

In French, nouns have gender (masculine or feminine) which is a grammatical feature. There isn't a specific reason why certain nouns are masculine or feminine, it's just a part of the language's structure. Learning the gender of nouns is important for correct grammar and agreement with other parts of speech.
