The germanic group of languages

The Germanic languages are a group of related languages that constitute a branch of the Indo-European(IE) language family. The common ancestor of all the
languages in this branch is Proto-Germanic, spoken inapproximately the mid-1st millennium BC in Iron Age northern Europe.
Proto-Germanic, along with all of itsdescendants, is characterized by a number of
unique linguistic features, most famously the consonant change known as Grimm’s
law.
