A verbal noun in Arabic can be equivalent to the gerund or infinitive in English. In Arabic, it is called the مَـصْـدَر (maṣdar), meaning ‘source.’
We have learned that derived forms take the triliteral abstract verb and add to it prefixes, suffixes, and infixes. The ten most common verb patterns in the past tense are:

Verbal Nouns of Pattern (1)
Verbs of Pattern (1) are generally considered unpredictable and require memorization and practice to identify their corresponding verbal nouns.
