The letter "È" is a character used in several languages, most notably in Italian and French. In Italian, it represents the open "e" sound, as in the word "caffè," meaning coffee. In French, it is used to indicate a specific pronunciation, as seen in words like "très," meaning very. The accent grave (`) over the letter "E" distinguishes it from its unaccented counterpart, "E." This accent can change the meaning of words and is essential for correct pronunciation. Understanding "È" is important for language learners to communicate effectively in Italian and French.
