Q. Subsequent to my Zaidy’s recent successful eye operation, he has developed a renewed interest in praying to Hashem. Upon viewing the siddur for the first time in many years, he asked me why the most important word pronounced is rarely printed. Additionally, the Posikim complain about the mispronunciation of the vowels of the Shem HaAdnus. As a remedy to this, he requested that I prepare a complete siddur with the following modifications:
1) Following every Shem Haviyah (except Ez.  18:23), write the Shem HaAdnus inside square parenthesis.
 2 Vocalize the Shem HaAdnus as it is found in Shoftim chap. 13, with a cholem mullay.
 Is there any reason not to create a siddur in this manner? Could anyone use it?

A. Horav Shlomo Miller’s Shlit”a opinion is that it is better not to write the Shem HaAdnus in its full version with an added vov, since it imbalances the gimatrias and numerical expressions inherent in the holiness of the name. Seeing the name written properly adds kedusha to the reader.
