Shavuot "sha-VOO-ote" in Hebrew. The word means "Weeks", probably because of the holiday's timing: It's the only holiday in the Torah without a date of its own, defined only as commencing seven weeks after the beginning of Passover. In 2011, Shavuot begins at sunset on Tuesday, June 7.

If you are asking what the Hebrew word for "Passover" is, it's pesakh (פסח). If you are asking for the meaning of the holiday, it is a celebration of freedom, commemorating the exodus from Egypt.
chag (×—×’) means "holiday" or "festival"
In Hebrew, the name of the holiday is not normally included in holiday greetings. You would just say Chag same'ach (חג שמח) which means "Happy holiday." A literal translation would be: Chag molad same'ach (חג מולד שמח).
