Abstract
Language is a phenomenon that has a central point within the field of linguistics. Among many aspects that are usually tackled within linguistics, the comprehension and the production of language are analyzed as well. Therefore, the two mentioned processes have a specific focus within the domain of linguistics. The ability to produce and comprehend language is usually examined by the speech input and output of speakers with brain damage. The current research tries to highlight a linguistic investigation by focusing on the speech comprehension and production of individuals with aphasia. That is why the aim of this research is to analyze the linguistic matters of spoken language input and output that are usually weakened as an outcome of brain damage such as stroke. In addition, the present work tries to reveal possible characteristics of aphasic speakers that show clear difficulties during speech input and output due to brain injury. The method of the study consists of semi-structured interviews with aphasic speakers that are collected by visiting a number of different public and private hospitals and physiotherapy centers in Erbil. The tests are done by using picture presentation techniques and a questionnaire related to background information of the participants. Aphasic individuals are shown a number of different types of pictures and are asked to answer specific questions related to the events within the pictures. Their linguistic state is then examined by analyzing their answer syntactically and semantically.

Summary
The human brain consists of specific areas that are responsible for processing all the abilities of the use of language such as reading, writing, listening and speaking. The outcome of language impairments due to brain injury is commonly known as aphasia. Aphasia is an acquired language disorder due to focal brain damage that must have occurred after the period of language development. The presence of aphasia is the result of several causes of brain damage whereas a cerebrovascular accident (CVA), known as stroke, is the most common one. By focusing on the location that is responsible of language use, and by depending on the size of the brain lesion, aphasia usually creates speech comprehension and production disorder (Reinvang, 1985). The most frequently used way to test the state of their language comprehension and production is syntactical
