"Hei" in the beginning of the word and "hei" at the end mean going in a certain direction, like in "הביתה" - "habaita" - as I like to translate it, "homewards." :)

But is there such word as "khutz"? Well, in theory - yes, but it's never used on it's own. I combination with prepositions - sure! Here are the examples:

For example:
קראתי את כל הספר, חוץ מהעמוד האחרון.
I've read the whole book, except for the last page.

Or, if you add "זה" ("this\it") it makes a perfect introductory expression "besides"!
For example:
חוץ מזה, כבר הבטחתי לה לא לספר לאף אחד.
Besides, I already promised her not to tell anyone.
That's it for this week!

Hope you are enjoying this newsletter,
Feel free to ask anything - something that wasn't clear in my explanations or just any question you might have about Hebrew - I'd be happy to answer! :)

Happy Hebrew-learning,
Alisa
