Do you spell your name with a “V,” Herr Wagner?
"but the guy to ask is Mr. Wiener. He is insists it's pronounced "WHY-ner." However, he is a wiener.
Also for FYI, most Indians who work in KSA speak an English Dialect called "Slow Googly." Among my duties there was translating this, usually welly welly wrong, for Texans and Oklahomans.
And never play squash with Pakistanis.
I took German about five years ago. Their alphabet has a "V" pronounce like an "F" and the "W" pronounced like the "V"--and English is a variation of German.
From the Internet: The English language has several roots, mainly the Germanic languages of the nations that invaded England in the first millennium A.D., particularly Angles and Saxons and Danes; and then Norman French (and via French, English has also strong roots in Latin).
The Scandinavian languages (except Finnish) are Germanic languages, as German and Dutch are.
==============================
So Herr Wagner is pronounced with a "V" sound, per their alphabet.
