[Facts] Re: Pronounce correctly X..ander
The only common English word where "X" at the start is pronounced like "ex" is X-ray, and that's because of the hyphen. Otherwise a word starting with "x" in English is normally pronounced with the "z" sound. If you want an alternative, it would be the pronunciation Ksander, using the normal sound of "x" in the middle of an English word. If you want this pronounced "Exander", it would be best to spell it that way or to use the hyphen, X-ander, as in X-ray.
