Instrument nouns (فَعَّالَة)

Arabic derives the names for modern machines, vehicles, and appliances from their base action verbs using a highly productive pattern: فَعَّالَة (Nouns of Instrument, or اسم الآلة).

The فَعَّالَة Pattern

To form these nouns, apply the فَعَّالَة pattern to a verb's root letters. This doubles the middle root letter (with a shadda), adds an alif, and ends with a taa marbuta (ة).

For example, from the root for "to dry" (ن-ش-ف), we derive the word for a clothes dryer:

Because they end in taa marbuta (ة), all nouns formed on this pattern are grammatically feminine. Any adjectives describing them must also be feminine.

Heavy Machinery and Office Tools

This pattern is extremely versatile and scales across all industries, from tiny office supplies to heavy construction equipment.
