Welsh orthography uses 29 letters (including eight digraphs) of the Latin script to write native Welsh words as well as established loanwords. The acute accent (Welsh: acen ddyrchafedig), the grave accent (Welsh: acen ddisgynedig), the circumflex (Welsh: acen grom, to bach, or hirnod) and the diaeresis mark (Welsh: didolnod) are also used on vowels, but accented letters are not regarded as part of the alphabet.
