Simplification

Purification

Examples

• Belgian – In 1844, 1864, 1946, 1996 and 2006.
• Catalan – In 1917 Pompeu Fabra published Diccionari ortogràfic, the first Catalan dictionary. The complete Diccionari General de la Llengua Catalana was published in 1931.
• Chinese
• * – replaced Classical Chinese with Vernacular Chinese as the standard written language, largely through the efforts of Hu Shih.
• * Mandarin was chosen at a committee from several Chinese dialects.
• * – changed the script used to write the standard language by introducing Simplified Chinese characters.
• Czech – The dictionary of Josef Jungmann contributed to the renewal of the vocabulary. In the 1840s the letter w was replaced by v.
• Dutch — In 1883, 1934, 1947, 1996 and 2006.
• Estonian – reform movement led by Johannes Aavik and Johannes V. Veski renewed the vocabulary, borrowing a lot of roots from Finnish and other Uralic languages and even inventing some roots.
• French — In 1740, 1762, 1835, 1992 by the Académie française.
• German – unified the spelling system nationwide. Further reforms were enacted more recently, in the German spelling reform of 1996.
• Greek – while the written "pure" language, the Katharevousa was full of Ancient Greek words, the spoken "popular" language, the Demotic Greek was not. After the fall of the military rule, a law was promulgated, making the latter the written language as well. For example, on Greek coins, the plural of the currency was drachmai before and became drachmes after 1982.
• Hebrew – Modern Hebrew was created from Ancient Hebrew by grammatical simplification according to Indo-European models, coinage of new words from Hebrew roots based on European models, and simplification of pronunciation rules. Linguist Ghil'ad Zuckermann argues that Modern Hebrew, which he calls "Israeli", is a Semito-European hybrid, based not only on Hebrew but also on Yiddish and other languages spoken by revivalists. Zuckermann therefore endorses the translation of the Hebrew Bible into what he calls "Israeli".
• Hungarian – more than ten thousand words were coined, thousands of which are actively used today.
• Irish – spelling system greatly simplified: Gaedheal became Gael, and Ó Séigheadh became Ó Sé.
• Japanese – historical kana usage was replaced by modern kana usage, while the kanji system also transformed from Traditional Chinese characters to New Characters.
• Norwegian – as Norway became independent from Denmark, Norwegians wanted a written language closer to spoken Norwegian. The reforms in 1907 and 1917 made Riksmål the written standard Norwegian, renamed Bokmål in 1929. Bokmål and the more vernacular Nynorsk were made closer by a reform in 1938. Today both language forms are written: on Norwegian coins, the name of the country is alternately Norge and Noreg.
• Portuguese – replaced a cumbersome traditional spelling system with a simplified one.
• Romanian – replaced Cyrillic script with the Latin alphabet, deprecated thousands of Slavic words in favour of Romance words. Romanian has undergone spelling reforms in 1904, 1953, and, most recently, in 1993, with two minor ones in 1964 and 2005.
• Russian – 1918 – Major changes in Russian orthography. Several letters were removed from Russian alphabet. Minor changes in Russian grammar. The reform has simplified some aspects of the language. Other reforms happened in 1708/1710 and 1956.
• Serbian — Slavonic-Serbian, the literary language of Habsburg Serbs, was disused with Vuk Karadžić's reforms and standardization as official language of Serbia.
• Somali – modified Latin script developed by a number of leading scholars of Somali, including Musa Haji Ismail Galal, B. W. Andrzejewski and Shire Jama Ahmed for writing the Somali language; made compulsory in 1972 by the President of Somalia, General Mohamed Siad Barre
• Turkish – language and writing system were reformed beginning in the 1920s, such that the older language is called by a different name: Ottoman Turkish. The Ottoman alphabet was based on the Arabic alphabet, which was replaced in 1928 by the new Latin-based Turkish alphabet. Loanwords of Persian and Arabic origin were dropped in favor of native Turkish words or new coinages based on Turkic roots.
• Vietnamese – Classical Chinese lost official status in 1918, and the colonial schools instituted a "Franco-Vietnamese Curriculum" at this time. Vietnamese was taught using the Latin alphabet, and this form soon became dominant.
