Iturritxu (a small spring or fountain in the Basque language) is the basic style, one letterform per character, using highly readable glyphs suited to text applications. It includes Latin characters for Western European, Central European and Baltic Languages, plus Romanian and Turkish.

Iturritxu 2020 is the feature-rich style for OpenType friendly applications. Designed to work especially well with the concave consonants and nesting vowels (KO, RO, TXO, ZO etc.) common in Basque (Euskara), the font also has many ligatures and contextual features for other languages such as English and Welsh. Much of the inspiration for the contextual forms comes from the compound consonants and vowel signs of North Indian scripts. Small capitals, old-style numerals (with optional swashes), sub and superscript numerals are all present. A PDF guide to the features is included in the 2020 package together with the basic Iturritxu font.

The Features Guide is also posted in the Gallery.
