Joseph:
The Hebrew you and I (would) speak is Lashon Hakodesh. Ivrit is what the Yordim speak (or what you may see on Israeli TV, but I wouldn’t know), with their slang and adapted Arab curses.
The only two languages that are “intrinsically” holy are Lashon Hakodesh and Aramis (e.g. Yigal Sahadusa, Daniel). Greek/Yevannis gets special metion for as per the the Gemorah in Megilla (Rav V’Shmuel 18a).
