Learn Arabic (Modern Standard): الذئب الأكول جائع دائما ويبحث عن خروف. - The gluttonous wolf is always hungry and looks for a sheep.

It is built from the root for eating, أ ك ل (a-k-l). By inserting these root letters into the فَعُول pattern, we get أكول (akool). This pattern expresses an intense or habitual trait, turning the basic concept of eating into the adjective "gluttonous" or "someone who eats excessively."

Why is there an الـ (al-) attached to الأكول?

This is a reminder of standard adjective agreement. Because "the wolf" (الذئب) is definite and starts with الـ, the adjective describing it must match. Thus, أكول becomes الأكول.

Why does the sentence use the active participle جائع (hungry) instead of an intensive adjective for that word too?

The word جائع describes a temporary physical state; the wolf is hungry right now. In contrast, الأكول uses the intensive pattern because being a glutton is a permanent, ingrained personality trait.

Why does the sentence use the preposition عن ('an) to mean "for" after the verb?

The verb يبحث (yabhath) means "he searches." In Arabic, the preposition عن (which often translates as "about") is the required companion for this verb. You don't look "for" something in Arabic; you search "about" it (يبحث عن).
