The noun of once (فَعْلَة)

On a movie stunt set, directors need to describe sudden actions and precise movements—a single jump, one strike, or a quick glance. In Arabic, expressing a single occurrence of an action is done using the Noun of Once (اسم المرة).

The Pattern (فَعْلَة)

To indicate that an action happened exactly one time, we use the pattern فَعْلَة. Apply this pattern to the three-letter root of a verb: the first letter takes a فتحة, the second takes a سكون, and the word ends with a تاء مربوطة.

Because they end in a تاء مربوطة, these nouns are feminine. They behave like any regular noun in a sentence—they can be subjects, take adjectives, or be the object of a preposition.

A common stylistic structure in Arabic pairs the Noun of Once directly with its matching verb in the same sentence.

While translating this literally to English sounds repetitive (e.g., "he jumped a jump" or "she looked a look"), it is highly idiomatic in Arabic. Using this structure emphasizes the single occurrence of the action, often by adding adjectives to describe exactly how it happened, or by adding the number واحدة for extra emphasis.

These nouns can also be used independently to describe an action that was seen or heard:
