What are diacritics in linguistics?
In linguistics, diacritics are marks or symbols added to letters to indicate specific phonetic qualities, stress, or pronunciation nuances in a language. Diacritics are commonly found in many languages around the world and serve to modify the sounds or meanings of the letters they are attached to.

They are often represented as accents, tildes, or dots. For example, in English, the diaeresis (¨) is a diacritic often used in words like “coöperate” to indicate that each ‘o’ is pronounced separately. They modify the base character to convey additional information about its pronunciation or usage in a particular context.
