You use the word “את” when describing something, usually a noun. It is sort of like the word “the”, but in a more specific form to describe a noun. You also use a hey(ה) while using the word “את”. So, you would say “את ה”.

For example, אני רואה את הנוף ,meaning, “I see the view.”

Another example is:אני קורא את הספר,meaning “I read the book.”
