Walloon orthography

The Walloon language has been written using various orthographies over its history, most notably the Feller system (sistinme Feller) and Common Walloon (rifondou walon or rfondou walon).

The Feller system was developed to transcribe Walloon dialects by Jules Feller and was first published in 1900. In the Feller system, the same word can be spelled differently depending on dialect: the word "fish" would be spelled pèchon by a speaker who pronounces the word as [pɛʃɔ̃] (with an 'sh' sound), but would be spelled pèhon by a speaker who pronounces the word as [pɛhɔ̃] (with an 'h' sound). In Common Walloon, however, the same word "fish" is always spelled pexhon, regardless of the speaker's pronunciation. The Common Walloon alphabet, developed through the 1990s, attempts to unify spellings across dialects, and revives some older graphemes (such as ⟨xh⟩) which were abandoned by Feller in favor of spellings which resembled standard French.

Early texts written in the region of Wallonia were composed in Medieval Latin, such as the 7th century Vita Sanctae Geretrudis. In the 9th century, the first texts written in the vernacular langue d'oïl appear in northern Gaul. One of the earliest of these documents, the Sequence of Saint Eulalia from around 880, shows regional traits of Walloon, Champenois, and Picard. The medieval written language, often referred to as the scripta, used spellings that represented the spoken language only approximately, and was full of latinisms and archaic forms. The scripta was not specifically Walloon, but rather, according to linguist Maurice Delbouille, this common written language "in its role as an inter-regional idiom opposed on one hand the Latin of the clergy and on the other hand the everyday local dialect in the various regions."

From the 13th century onward, the scripta used in Wallonia was increasingly influenced by the "central" dialect of Île-de-France. In an analysis of a document from 1236 Liège, the linguist Louis Remacle found that only about 15% of the vocabulary used was distinctively Walloon, with the rest either distinctly French or having a phonetic form common to all the langues d'oïl. From this time forward, writing in Wallonia underwent "cycles of purification", moving progressively closer and closer to the standard of the French language.

Even as the literature of Wallonia became almost entirely French through the 14th and 15th centuries, some Walloon words could still be found in local writing. A medical text from the early 15th century displays the situation by using the Walloon weris "healed" alongside the Middle French garira "will heal". Walloon toponyms and proper nouns, as well as some words for common objects could be found written in dialect, often spelled in distinctive ways, using graphemes like ⟨xh⟩ and ⟨ea⟩.

Beginning around 1600 some of the first "truly" Walloon documents appear, mostly in the Liège dialect. These include letters, poems, and works commenting on religious and political affairs. Spelling during this early period was inconsistent, as evidenced by different published names of the 1757 opéra comique Li Voyèdje di Tchaufontainne:

Despite the variety of spellings, some conventions were followed by many of these early texts. For example, ⟨j⟩ or ⟨g⟩ (before e and i) were often used for the sound [dʒ], and similarly ⟨ch⟩ represented [tʃ], while later orthographies would use ⟨dj⟩ and ⟨tch⟩ respectively. Many Walloon texts of this era also continued the usage of traditional digraphs such as ⟨xh⟩.

The 19th century saw a flourishing of Walloon literature. In 1856 the Société liégeois de Littérature wallonne (Liège Society of Walloon Literature) was founded, later renamed the Société de Langue et de Littérature wallonnes [wa; fr] (Society of Walloon Language and Literature, SLLW). The Society promoted artistic works in the Walloon language as well as works of philology and dialectology. From the beginning, the SLLW was interested in solving the issue that there was no unified system of spelling for the Walloon language. Several orthographies were proposed, such as the more phonemic orthography of Charles-Nicolas Simonon (using such novel letters as ⟨ɹ⟩ and ⟨ñ⟩) and the orthography of Nicolas Pietkin, which made extensive analogy with French orthography. The most influential proposal, however, was that of dialectologist Jules Feller, the creator of the Feller system.
