A poem is a piece of writing in which the words are arranged in separate lines, often ending in rhyme, and are chosen for their sound and for the images and ideas they suggest.

The oldest surviving epic poem, the Epic of Gilgamesh, dates from the 3rd millennium BCE in Sumer (in Mesopotamia, present-day Iraq), and was written in cuneiform script on clay tablets and, later, on papyrus.

English Grammar Terms III

In linguistics, the grammar of a natural language is its set of structural constraints on speakers 'or writers' composition of clauses, phrases, and words. The term can also refer to the study of such constraints, a field that includes domains such as phonology, morphology, and syntax, often complemented by phonetics, semantics, and pragmatics. There are currently two different approaches to the study of grammar, traditional grammar and theoretical grammar.
