How do you say Never Again in Hebrew?

Answer 1

le-olam lo od (לעולם לא עוד)

you can also say: khas vekhalilah (חס וחיליה) which roughly means "heaven forbid".

Answer 2

You would write it מורה when referring to the word for teacher, as I assume that is what you are looking for.

Answer 3

Never (in the future) le-olam lo... (לעולם לא)

Never (in the past) me-olam lo... (מעולם לא)

Answer 4

"לא עוד" (pronounced "Lo od").
