The term 'kind of accent' can refer to three different types of accents: ACUTE (5 letters), GRAVE (5 letters), and BURR (4 letters). ACUTE accents are used in languages such as French and Spanish to indicate a change in pronunciation, usually a stressed syllable. GRAVE accents are also used in French and Spanish to indicate a change in pronunciation, but they are used to indicate a lower tone than an ACUTE accent. Finally, a BURR accent is a type of Scottish accent that is characterized by a rolling of the 'r' sound.
