Diacritics
Diacritics are symbols or marks added to letters to alter their pronunciation or to distinguish them from similar letters in a writing system. They are commonly used in various languages around the world. For instance, in Spanish, the tilde (~) is used as a diacritic mark over the letter "n" in words like "mañana" to indicate a different pronunciation ("ny" sound). In French, accents such as the acute (´), grave (`), and circumflex (^) are used to indicate variations in vowel pronunciation or stress, as in "é", "à", and "ê". Diacritics can also be found in non-alphabetic scripts like Arabic and Devanagari, where they serve similar purposes of altering pronunciation or distinguishing characters.
