Al-Mubtada’ المُبْتَدَأُ (The Subject) in Arabic Grammar

Understanding Al-Mubtada’ (The Subject) in Arabic Grammar

Welcome to today’s lesson on Arabic grammar! If you're learning Arabic, understanding Al-Mubtada’—or the subject of a nominal sentence—is crucial. This concept forms the foundation of many Arabic sentences, and mastering it will significantly improve your fluency. In this blog post, we’ll break it down step by step, making it easy for you to grasp. Let’s get started!

What is Al-Mubtada’?

In Arabic, sentences can be categorized into two main types:

• Verbal sentences (الجملة الفعلية) – These sentences start with a verb.
• Nominal sentences (الجملة الاسمية) – These sentences start with a noun or pronoun.

The Mubtada’ (المبتدأ) is the subject of a nominal sentence. It tells us who or what the sentence is about.

For example:

• الطالبُ مجتهدٌ (At-tālibu mujtahidun) – “The student is hardworking.”
  • Mubtada’ (Subject): الطالبُ (The student)
  • Khabar (Predicate): مجتهدٌ (Hardworking)

As you can see, the Mubtada’ is the word that introduces the topic of the sentence.

Characteristics of Al-Mubtada’

The Mubtada’ has some important characteristics:

1️⃣ It is always a noun or pronoun

The Mubtada’ must be a noun, a proper name, or a pronoun.

2️⃣ It is usually definite

In most cases, the Mubtada’ is definite, meaning it has Alif and Lam (ال) or is a proper noun.

3️⃣ It appears at the beginning of the sentence

Unlike English, where subjects can sometimes appear later in the sentence, in Arabic, the Mubtada’ always comes first in a nominal sentence.

Examples:

• الكتابُ جديدٌ (Al-kitābu jadīdun) – "The book is new."
• هوَ طيّبٌ (Huwa ṭayyibun) – "He is kind."

In both cases, the first word is the Mubtada’, and it introduces the main subject of the sentence.

Agreement in Gender and Number

In Arabic, the Mubtada’ and the Khabar (the predicate) must match in gender (masculine or feminine) and number (singular, dual, or plural).

Examples:

✅ الطالبةُ مجتهدةٌ (At-tālibatu mujtahidatun) – "The female student is hardworking."
✅ الطلابُ حاضرون (At-tullābu ḥāḍirūn) – "The students are present."

In both examples, the predicate agrees with the subject in gender and number.

Special Cases of Al-Mubtada’

Sometimes, the Mubtada’ can be indefinite, especially in certain expressions or when used in a question.

Examples:

• سؤالٌ مهمٌ (Su’ālun muhimmun) – "An important question."
• من المسؤول؟ (Man al-mas’ūl?) – "Who is responsible?"

In these cases, the Mubtada’ doesn’t follow the usual definiteness rule, but it still functions as the subject of the sentence.

Conclusion
