Grave accent
The grave accent (`, ◌̀) ( GRAYV or GRAHV) is a diacritical mark used to varying degrees in French, Dutch, Portuguese, Italian, Catalan and many other Western European languages as well as for a few unusual uses in English. It is also used in other languages using the Latin alphabet, such as Mohawk and Yoruba, and with non-Latin writing systems such as the Greek and Cyrillic alphabets and the Bopomofo or Zhuyin Fuhao semi-syllabary.
