Why was the river tyne called tyne?

There are multiple theories about the origin of the name "Tyne". One common theory is that the name is derived from the Celtic word "Tawn", meaning "river". Another theory is that the name is derived from the Old English word "Tine", meaning "flowing water". Finally, some believe that the name is a combination of the Celtic word "Tawn" and the Old English word "Ea", meaning "water".

Due to the lack of concrete evidence, it is difficult to say with certainty which theory is correct. However, each of these theories provides a possible explanation for the origin of the name "Tyne".
