There is no letter "J" in the Hebrew language, so Jehovah is grammatically impossible.
--Edit--
Except of course Hebrews didn't say "Jehovah" - that is the English translation of the name - they said something more like 'Yahweh', from the Hebrew version of God's name: YHWH (there are no vowels in ancient Hebrew). Most languages have their own version or translation of God's name, so this is not a uniquely English issue. For example:
Albanian: Zoti
Azerbaijani: Yehova
Basque: Jehobaren
Bulgarian: Ĭekhova
Chinese: Yēhéhuá
Croatian: Jehova
Czech: Jehova
Danish: Jehova
Dutch: Jehova
Estonian: Jehoova
Filipino: Panginoon
Finnish: Jehova
French: Jéhovah
Galatian: Xehová
German: Jehovas
Greek: Iechová
Hindi: Jēnōvā
Hungarian: Jehova
Icelandic: Drottinn
Indonesian: Yehuwa
Italian: Geova
Japanese: Ehoba
Korean: Yeohowa
Latvian: Jehova
Lithuanian: Jehova
Macedonian: Jehovinite
Norwegian: Jehova
Polish: Jehowa
Portuguese: Jehová
Romanian: Iehova
Russian: Iegova
Serbian: Jehova
Slovak: Jehova
Slovenian: Jehova
Spanish: Jehová
Swedish: Jehova
Thai: Phra ya ho wá
Turkish: Yehova
Ukranian: Yehova
Obviously, all are pronounced differently, but their meaning is the same. Just like the difference in names between English and French for example. Peter is the same as Pierre, John is the same as Jean, and so on.
The pronunciation issue is the same with the name Jesus. Most likely the Jews at that time pronounced this more like 'Yeshua' or 'Yehoshua', but the accepted English translation is Jesus and no-one seems to have a problem with this. Again, different languages have their own translation.
Jews did develop a superstition over pronouncing the divine name, but this would not have been the case in ancient times given that the name appears well over 6,000 times in the original Old Testament manuscripts.
The name Jehovah was included four times in the English King James or Authorised Version of The Bible. You can usually find it at Psalms 83:18, however more recent revisions have the name removed. Up until the first half of the twentieth century, the name Jehovah was still in common use amongst members of many religions, however few today still use the name, with the obvious exception of Jehovah's Witnesses of course.

jehovah
No they do not.
"Jehovah" in Russian is "Иегова" (Yehova).
Jehovah's Witnesses started with Abel, one of Adam and Eve's sons who was killed by Cain. The Bible may not say directly that he was a 'Jehovah's Witness', but it does say he was a witness to God.
They can. There is nothing to say they can't.
me encanta Jehova
Well, we Jehovah Witnesses take care of our safety. We try to stay away from people we are not too sure of, and if the person who invited the Jehovah's Witness member is not a Jehovah's Witness, we say no. However, if it is a Jehovah Witness who invited a Jehovah Witness to a sleepover, it depends.
Jehovah is a name for God. Catholics believe in God. They just don't generally use Jehovah as a name for God, but it is the same God. So yes, you could say that Catholics believe in Jehovah.
I have had a good look and can not find any thing to say if he is or is not one of Jehovah's Witnesses.
JHWH In english, we say Jehovah.
Yes; Jehovah's Witnesses have nothing against gift giving or receiving. They do not celebrate pagan holidays.
People say they heard him speaking poorly about the Jehovah's Witnesses. I dont believe everything I read on the net. There is no evidence supporting or refuting the suggestion he is a Jehovah's Witness.
