ليس is not a verb my friend

These are two interesting videos on Arabic verb conjugation:

Hi Vanessa, I hope you can find Arabic easy! :)

Look! There are some verbs in Arabic which we can't conjugate its tense (for sure we can for the person and the number). Those verbs called the "Incomplete verbs" (You may find another name for them. By the way this name means they don't work as a normal verb with a complete role). This verb is one of them, and it doesn't have a meaning alone itself, but it needs to be in a sentence. This verb is added to the normal "noun clause" to make it negative. For example we could say "الرجلُ طويلٌ" this means "The man is tall", however, if we add "ليس" to this noun clause we make it negative like that "ليس الرجلُ طويلًا" and this means "The man is <em>not</em> tall". Yet if you notice a small thing, when we add "ليس" we make a small change to the original clause, so <em>usually</em> the noun which is close to "ليس" ends with " ُ " or anything serves the same work like " و " or " ا " in some cases- which are not important for you at this moment and you can ignore them now, but it's cool to keep this in mind for the close future- and make the other noun, which is far from it, ends with " َ " or anything serves the same work, like " ي " or " ا " in some cases and just ignore them now.

I hope I put it clearly for you.

There are plenty of good resources that explain the in and outs of Arabic verbs in great detail but as a beginner, it might be best to first stick with the very basic stuff. Here‘s an italki article on Arabic verb conjugation: <a href="https://www.italki.com/article/742/an-easy-way-to-explain-the-present-tense-conjugation-of-arabic?hl=de" rel="noopener noreferrer" target="_blank">https://www.italki.com/article/742/an-easy-way-to-explain-the-present-tense-conjugation-of-arabic?hl=de</a>;

The one I'm using, The table, page 87 of the pdf (75 of the book):

and two chapters, page 429 (417) and 489(477):

I understand that it is not what you need, but why not. Arabic grammars tend to be wirten in a heavy language. This one is easier, but still it is a "thick" book.
