Welcome to Etymology.ch!

This is a website about the etymology of common, everyday words from Indo-European languages. It tries to present etymological information in novel and surprising ways, using the power of modern web browsers. (Find more about these ambitions on the About page.)

One approach used here consists of etymology trees that show all words that developed out of single roots over the course of several thousand years. You can see a small part of such a tree below. (There are other websites that offer such trees, but not in this size and degree of completeness.) So far there are the following trees:

The (mostly completed) tree for the reconstructed root for water: *wed-
The (mostly completed) tree for the reconstructed root for red: *h₁rewdʰ-
The tree for the reconstructed root for 7, i.e. the number seven (work in progress): *septḿ̥

The second feature here that is ready to use: An Etymological Text Analyzer for English that is not restricted to single words, but looks up whole text passages in one go and colors each word according to Germanic or Romance descent. As an example, get the 100 most frequent English words analyzed and see that nearly all of them are Germanic: English Top 100

The third feature: The Cognate Checker which lists cognates (words of common origin) in Germanic languages like English and German and can also list words that made it from the common Germanic ancestor language into one, but not the other modern language.

The following is an example of an etymology tree: Its root is a word watōr that was reconstructed as the common ancestor of the "water" words of all Germanic languages, like English, German, and the Nordic languages:

In the tree you can click on the blue words to see some details about them, and likewise on the blue-green language names. (The full tree for water is here: *wed-)
