Base verbal nouns (المصدر)

What is a Verbal Noun (المصدر)?

In Arabic, the verbal noun (المصدر) represents an action or idea independent of time. In English, these correspond to "-ing" or "-tion" words (like "arriving" or "arrival"), as well as abstract concepts (like "success" or "justice").

Unlike derived verbs (Forms II through X), the verbal nouns for basic Form I verbs are unpredictable. You must memorize the verbal noun along with each new Form I verb.

Here are three common Form I verbal noun patterns:

Abstract Concepts and the Definite Article

Because verbal nouns are true nouns, they behave exactly like regular nouns in a sentence. When speaking about an abstract concept in a general sense—such as justice, patience, or knowledge—you must attach the definite article (ال). For example, "Justice is important" is literally "The justice is important."

Using Verbal Nouns for Actions and Events

Verbal nouns are heavily used to describe events or the act of doing an action. You will frequently see them in a possessive construction (إضافة) or following prepositions (like "before" or "after") instead of a full verb phrase. For example, rather than saying "before he exits," Arabic often uses "before exiting."
