As a language, English is derived from the Anglo-Saxon, a West Germanic variety, although its current vocabulary includes words from many languages. The Anglo-Saxon roots can be seen in the similarity of numbers in English and German, particularly seven/sieben, eight/acht, nine/neun and ten/zehn. Pronouns are also cognate: I/ich; thou/Du; we/wir; she/sie. However, language change has eroded many grammatical elements, such as the noun case system, which is greatly simplified in Modern English; and certain elements of vocabulary, much of which is borrowed from French. Though more than half of the words in English either come from the French language or have a French cognate, most of the common words used are still of Germanic origin.
