The letter "è" is a character used in several languages, most notably in French and Italian. It represents a specific vowel sound, often pronounced as an open "e" sound, similar to the "e" in "bed." In French, "è" is commonly found in words like "très" (very) and "père" (father), where it indicates a change in pronunciation compared to the regular "e." In Italian, "è" serves as a distinct letter that can change the meaning of words. For example, "è" means "is," while "e" means "and." The accent on "è" helps clarify pronunciation and meaning, making it an essential part of the language's written form.
