Welcome to Featured Wiki of the Day, your daily dose of knowledge from Wikipedia’s finest articles.
The featured article for Friday, 22 November 2024 is Weise's law.
In historical linguistics, Weise's law describes the loss of palatal quality some consonants undergo in specific contexts in the Proto-Indo-European language. In short, when the consonants represented by *ḱ *ǵ *ǵʰ, called palatovelar consonants, are followed by *r, they lose their palatal quality, leading to a loss in distinction between them and the plain velar consonants *k *g *gʰ. Some exceptions exist, such as when the *r is followed by *i or when the palatal form is restored by analogy with related words. Although this sound change is most prominent in the satem languages, it is believed that the change must have occurred prior to the centum–satem division, based on an earlier sound change which affected the distribution of Proto-Indo-European *u and *r. The law is named after the German linguist Oskar Weise, who first postulated it in 1881 as the solution to reconciling cognates in Ancient Greek and Sanskrit.
