You’ve probably noticed by now that most words in Arabic have three-letter roots, while some have four or even five.
But there are also examples with two-letter roots, often referring to family members or body parts. Let’s take a look at some of them:
What are the 5 special nouns in Arabic?
Five nouns with two-letter roots are considered special because they take a long vowel instead of a short one when annexed or when a personal pronoun suffix is attached.
Depending on the grammatical case, they take:
و (-uu) for the nominative
ا (-aa) for the accusative
ي (-ii) for the genitive
These five nouns are:
The most commonly used of these are: أب
(father), أخ
(brother), and ذو
(owner / possessor of). Now let’s see how they change:
One important point to highlight is that the personal pronoun suffix comes after the long vowel, and the pronoun for the first person is ي (-ii) or ني (-nii).
So, if I want to say “my father” (or any word ending in u, short or long), the i wins.
Examples:
أبو
+ أنا
→ أبي (aby – my father)
حُلمُ
+ أنا
→ حُلمي (hulmy – my dream)
Why? Because u + i = ي. Even a short u shifts and becomes ي.
This is extremely important to remember, especially since in many dialects, to say “my father” you simply keep the و:
Dialect: أبوي (abuy)
Standard Arabic (MSA): أبي (aby) — the و is dropped.
The same applies for “my brother”:
Dialect: أخوي (akhuy)
Standard Arabic: أخي (akhy).
Let’s look at some more examples:
Now, moving on to ذو, which means “owner” or “possessor.” This word is always followed by the genitive case, and its feminine form is ذات.
