In Eritrea they are different dialects of Tigrinya and their is no what you call " Eriteria Tigrinya". The Welkait Tigrinya is one of the dialects of Tigrinya and the 1849 map discovered recently has exposed the lies of this man and his kinds on their claim Welkait was not part of Tigray. Abiy as part of his confuse & deceive " divide and rule strategy" was also recently lying about who the owners of the Axumite civilization are!
