Poetry is a distinct human activity, linked in one way or another to the nature of the poet psychologically, intellectually, historically and artistically. The poet Ahmed Jarallah Yassin is a professor and doctor of Arabic language and literature. He is distinguished by his playing with many literary genres. He is a poet, storyteller, painter, and critic. He has a distinguished academic presence and has won many awards in various artistic and research fields. Among that activity was his prolific output in poetry, as he wrote seven poetry collections, most of which were prose poems, and dealt with life issues with confident language and conscious thought about what he was saying. The collections of his printed poetry were chosen to be texts because we were engaged in a morphological-grammatical study concerned with derivative description, and choosing the predicate as a model for this derivative description. We cannot fail to mention that Ahmed Jarallahs poetry seems easy to read, but it requires a second and third reading and careful consideration.
