Ism al-Fi’l (اسم الفعل): Understanding Arabic’s Unique “Nouns with Verbal Force”

The phrase حَيَّ عَلَى الصَّلاةِ (ḥayya ʿalā ṣ-ṣalāh), meaning “Come to prayer!” in Islam, exemplifies a special kind of Arabic word: a noun that shares characteristics of verbs and carries their meaning, time, and function.

This article delves into these unique “nouns with verbal force” (اسم الفعل), explaining their indeclinable nature, their ability to govern other words, and common imperative examples like صَهْ (hush!) and آمِينَ (Amen!).

Let’s start our analysis of حَيَّ عَلَى الصَّلاةِ by examining the word حَيَّ.

The special features of حَيَّ

Let us first look at the characteristics of the word حَيَّ.

• Such a word is not a pure noun (اِسْم) only. Why? Other than nouns, a اِسْم الْفِعْل only conveys a meaning on itself when it is linked to time.
• We also don’t call it a pure verb be­cause it does not carry the signs and markers of a verb, i.e., the usual endings.
• All forms of a اِسْم الْفِعْل are indeclinable (مَبْنِيّ).
• Furthermore, it is not affected by other parts of the sen­tence. In other words, it does not have a regent (عامِل) and doesn’t have a po­sition in إعراب.
• However, a اِسْم الْفِعْل has governing power of a verb and works as a regent (عامِل). It can govern other words and in­duces cases – note the cases after such a word.
• Therefore, it can carry a direct object (مَفْعُول بِهِ) in the accusative case (مَنْصُوب). This object, however, can never precede the اِسْم الْفِعْل. It has to be placed after.

In Arabic grammar books, the اِسْم الْفِعْل is classified by the tense/time it relates to. Therefore, we have three types (imperative, past tense, present tense).

I only focus on the imperative here as this is the most common type.

Nouns with imperative force (اِسْم فِعْل أَمْر)

Many exclamations have a cer­tain verbal force and are given the equivalent of an imperative.

Remark: Christians use Amen a lot. Amen is probably of Aramaic origin: אמין, meaning strong, enduring, true, last­ing, eternal. In Hebrew, אָמֵן means so be it; truly. From Hebrew, it perhaps en­tered ancient Greek (ἀμήν) and from where it spread to other languages.

Muslims say ’Āmīn as well, for example, after having read the first Sura al-Fātiha (سُورةالْفاتِحة).

Some linguists suggested that the آ – the Aleph Madd (أَلِف مَدّ) – is only there in the word آمِينَ to provide the fullness of the sound “a” (فَتْحة). What supports this idea is the fact that there is no word in Ara­bic following the pattern فَاعِيلٌ.

Many common expressions fit into this category.

They were origi­nally preposi­tional phrases (الْجَرّ وَالْمَجُرور) or adverbs of place (ظَرْف مَكان) but now have the meaning of an imperative. Grammari­ans call such expressions a اِسْم فِعْل مَنْقُول (transferred).

Notice in the examples the direct objects – the accusative case (مَنْصُوب)!
