DESCRIPTION

The Na-Dené (Athabaskan–Eyak–Tlingit) family of languages are found across western North America, from Alaska to México. There are a variety of contemporary transcription methods for these languages: the most popular in the United States requires the acute and ogonek accents. Diné Bizaad (Navajo) – the most popular Na-Dené language in use – relies on the acute/ogonek transcription method for typeset text.

Accents are used predominantly on vowels, and are a form of guidance on suitable pronunciation. The acute accent indicates a raised tone, and the ogonek indicates adding a nasal tone. Therefore:

• a = normal tone, oral only • a-acute = higher tone, oral only • a-ogonek = normal tone, oral & nasal • a-acute-ogonek = normal tone, oral & nasal

These accents are used on all five standard vowels (a, e, i, o & u). Some Na-Dené use additional accented consonant characters, such as ‘n-acute’ in Diné Bizaad.

Na-Dené languages always use a centre-positioned ogonek accent on characters, rather than the right-aligned position used in Europe by languages like Polish. Because few typefaces include support for centre-positioned ogonek accents, it has become customary to typeset Na-Dené using right-aligned ogonek accents as a last resort.

The Source family of typefaces already includes partial support for Na-Dené accented characters, but could be improved by adding centre-positioned ogonek accent support for the following characters:

• A-ogonek • A-acute-ogonek • E-ogonek • E-acute-ogonek • I-ogonek • I-acute-ogonek • O-ogonek • O-acute-ogonek • U-ogonek • U-acute-ogonek • a-ogonek • a-acute-ogonek • e-ogonek • e-acute-ogonek • i-ogonek • i-acute-ogonek • o-ogonek • o-acute-ogonek • u-ogonek • u-acute-ogonek
