Superlative adjectives (أفعل)

The Superlative Pattern (أفعل)

You already know that the pattern أفعل is used to create comparative adjectives (like "bigger" or "faster"). Arabic uses this exact same pattern to express the superlative degree—meaning "the biggest," "the fastest," or "the most beautiful."

Forming the Superlative with Idafa

To say "the most beautiful city" or "the oldest mosque," place the أفعل adjective before the noun it describes. This links the two words together in an Idafa (possession) construction.

When forming this construction:

• Use the fixed أفعل pattern.
• Follow it immediately with a singular noun.
• Do not use the definite article (ال) on either word. The phrase automatically translates with "the" in English.

Just like in the comparative form, the superlative adjective never changes for gender or number. Notice how in the first example, مدينة (city) is feminine, but أجمل remains in its base form.

Superlatives in Context

Because this is an Idafa phrase, the entire unit (Superlative + Noun) acts as a single block. It can appear anywhere in a sentence: as the subject, the object of a verb, or following a preposition.

Irregular Roots in the Superlative

Some adjectives are built from roots with weak letters (like ي or و) or doubled letters. When fit into the أفعل pattern, their endings look slightly different (such as أعلى for "highest", أغنى for "richest", or أهم for "most important"), but they follow the exact same grammatical rules.
