Vennemann posits that starting in the fifth millennium BCE, Atlantic/Semitidic seafaring colonizers (related to Semitic speakers) settled the coastal regions of Western and Northern Europe.

This "substrate" influenced the vocabulary and structure of the languages that eventually replaced them.

Vennemann argues that after the last Ice Age, much of Western and Central Europe was inhabited by speakers of Vasconic languages , of which Basque is the only surviving member.

While provocative, Vennemann's theories are highly debated and generally rejected by the mainstream linguistic community. Critics often argue that:

Structural similarities like VSO word order may be typological coincidences rather than proof of direct contact.

He identifies structural similarities between Insular Celtic languages (like Irish and Welsh) and Semitic/Hamitic languages, such as Verb-Subject-Object (VSO) word order.

He even suggests these colonizers significantly impacted the development of Germanic languages , influencing everything from the invention of runes to the origins of deities like the Vanir . Academic Reception
