In Arabic, not all sentences need a verb to be complete. Many sentences start with a noun, and these are called nominal sentences, or Jumla Ismiyya (جملة اسمية). This structure is fundamental to Arabic and is used constantly to describe people, places, and things.

A nominal sentence has two core parts: the subject, called the Mubtada' (مبتدأ), and the predicate, called the Khabar (خبر). The Mubtada' is what the sentence is about, and the Khabar tells us something about the Mubtada'. Think of the Mubtada' as the topic and the Khabar as the news or information about that topic.

One of the most interesting features of a nominal sentence in the present tense is the absence of the verb 'to be'. You don't write a word for 'is' or 'are'. The relationship is simply understood. For example, to say "The teacher is new," you just say "The teacher new."

So how does Arabic distinguish between a complete sentence like "The house is big" and a simple phrase like "a big house"? The key is in whether the nouns are definite (Ma'rifa) or indefinite (Nakira).

In a nominal sentence, the subject (Mubtada') is almost always definite, while the predicate (Khabar) is indefinite. This structure is what signals that you're reading a complete thought.

A noun is made definite by adding the prefix الـ (al-), which works like 'the' in English. A noun is typically made indefinite by adding a diacritic called tanwin (تنوين) to the end. Tanwin adds an '-n' sound (un, an, or in) to the end of the noun and signals indefiniteness, like 'a' or 'an' in English.

Notice the pattern: Definite subject plus indefinite predicate equals a full nominal sentence. If both are indefinite, it's just a descriptive phrase.

Just like in many other languages, nouns in Arabic have grammatical gender, either masculine or feminine. A key rule in nominal sentences is that the predicate must agree in gender with the subject.

Many feminine nouns end with the letter ة, called taa marbuta. Adjectives are made feminine by adding this same ending.

In the feminine example, both the subject الطَّالِبَةُ (the student) and the predicate ذَكِيَّةٌ (smart) end with taa marbuta to show agreement. This is a consistent rule you can rely on when building your own sentences.
