Hi new to this site - Has anyone every heard of the girls name Amitiel - shes an archangle. If so does someone know how to pro-nounce it correctly?

In the various lists of Archangels, Amitiel is never mentioned as being one of them.
Amitiel is listed to be an angel of truth, but that's about it.

Amitiel: The angel of truth. He can be called upon for help in any matters requiring honesty and integrity.

I have looked a lot of sites and cannot find a pronounciation for you. Maybe some one else can.
my guess would be Ama-teal ot Ah-me-shul, but it is only a guess

I've heard of the hebrew name Amital. It's unisex in Israel, and pretty popular there, along with it's variants--- Avital and Abital.

Ah Mee Tall

It means "father of dew" or "precious dew".

Names with the word "tal"(meaning dew) in them are popular in israel because it's so dry there and they get pretty excited about dew!

Other "dew" names.

Tal - dew
Talia/Talya - G-d's dew
Tali - my dew
Talora/Talori - morning dew
