Hebrew is not a Latin language; one only needs to open a Bible to realize this. Therefore, learning this language requires first learning its alphabet or rather its “Alef-Beth.”
Beginners are those who have learned Hebrew at Talmud Torah, for Bar Mitzvah preparation, by tradition at the synagogue, or even in a religious school, but who do not know how to speak it.
Beginners often know how to write even in cursive. They have everything to start learning Hebrew with confidence.
A good Hebrew course (like Hebrew Live) will allow you to start expressing yourself in Hebrew and even quickly read without vowels.
