"À" is a preposition in the French language that translates to "to" or "at" in English. It is commonly used to indicate direction, location, or time. For example, one might say "Je vais à la maison" (I am going to the house) or "Rendez-vous à trois heures" (Meet at three o'clock). In addition to its basic uses, "À" can also be part of various expressions and idiomatic phrases. It is often combined with definite articles to form contractions, such as "au" (à + le) and "à la" (for feminine nouns). Understanding "À" is essential for mastering French grammar and communication.
