How is God's name pronounced when there is a prefix?
The 4 letter name for Hashem is replaced with the word a/d-/nai (3 syllables). But my siddur doesn't put vowels under each instance, so I'm not sure how to say the word when it is preceded b a prefix lake a vav, a lamed or a beit.
The word "e/l-/kei" becomes vei/l-/kei with the addition of the preceding vav -- the vowels under the aleph disappear and the word stays 3 syllables. Is the same true for Hashem's name? Does it become
va/a/d-/nai and become 4 syllables?
