السلام عليكم ورحمة الله وبركاته
Peace be upon you, brothers and sisters. If you need any help with Arabic, I am here to help as it is my native tongue.
To start with, the most difficult thing with Arabic would be its morphology (word structure). Arabic is a Semitic. Semitic languages are known for their Non-concatenative Morphology, this term is very important to understand and here is why:
English is a concatenative language, in that, the roots of the words are mostly in tact (with a few exception). For example, to form a plural in English, one mostly just add -s at the end. So:
Cat > Cats
Or how to form a past tensed verb, you mostly put -(e)d after the verb, as in
Play > Played
But this is not the case in Arabic and the Semitic languages, oh no. The root
shadjarah (tree, singular) شَجَرَة
ashdjaar (tree, plural) أَشجَار
Here, the root are the consonants SH-DJ-R ش-ج-ر
The singular form is of the template CaCaCah, (C is for consonant), while the plural form is of aCCaaC. Templates are very important in such languages and it is best that you try to memorize them. The word tree in Arabic is in the class of nouns called "the broken plural" because vowels surround the roots differently.
The same thing happens with verbs. In Arabic, verbs are classified as perfective and imperfective verbs. For example, the verb for "kill" is formed with the "kill" root, the 3 consonants q-t-l ق-ت-ل
In the perfective, usually the template is to add an A after each consonant to get the template CaCaCa, so for a verb "killed", it will be:
qatala = "he killed"
But the imperfective has a different structure and is mostly more complex, so for he kills it will be:
yaqtulu = he kills
yaCCuCu
Try to apply the same logic to the root for drink, SH-R-B ش-ر-ب
sharaba = he drank
yashrabu = he drinks
Note that there are some nuances, like the template for the imperfective form of drink is yaCCaCu, instead of kill which has yaCCuCu in the imperfective. But hopefully you will get them in no time. I'll try to make another post later for verb morphology and agreement (I eat, you eat, he eats etc).
May Allah ease this learning on you, anon brothers and sisters.
