In each of the consonant/vowel letters of the Ancient Hebrew language the pronunciation of the consonant is closely related to the pronunciation of the vowel such as the letter “hey” (See above) is “h” and “eh” and the pronunciation of the letter “yud” (See below) is “y” and “iy”.

Therefore, the original name of this letter would have been “waw” instead of “vav”.
