Again, I am not saying they are not as thet are in the tetragrammaton... but rather that they are unique in tetragrammaton.
Who besides myself? Among Jews, the tetragrammaton is referred to as “The unpronounceable name of God.” Look up any Jewish source about YHWH. For instance, http://www.theshalomcenter.org/index.php?q=node/576
Read here about the Qere Perpetuum:

Rabbinical traditions, as Maimonides discusses, about not pronouncing God’s name may be interesting but they are hardly a guide to whether or not God’s name should be pronounced or have a substitute word read when it’s encountered. As for God’s name being unpronounceable, since it was incorporated into many other names that could be so or their names would likewise be unpronounceable. As the Dead Sea Scrolls copy of the book of Isaiah shows, God’s name was used frequently and freely and there is no Biblical reason we should not also do so even if our pronunciation is imperfect. And of course our pronunciation is not the pronunciation Moses or Abraham heard as this comment from Wikipedia explains “Another example of an important qere perpetuum in the text of the Bible is the name of the God of Israel — יהוה (cf. Tetragrammaton) — which is marked with the vowels of ×Ö²×“Ö¹× Ö¸×™ adonai (meaning “my Lord”) rather than with its own vowels (sometimes with the vowels of ×Ö±×œÖ¹×”Ö´×™× elohim).” Neither Yahweh or Jehovah is the correct pronunciation of God’s name but both can be derived from the Tetragrammaton and are familiar to most readers so we come as close as we can with the information we have.
