Language Pathology

Language is a system that consists of the development, acquisition, maintenance and use of complex systems of communication, particularly the human ability to do so; and a language is any specific example of such a system.

Pathology (from the Greek roots of pathos (πάθος), meaning "experience" or "suffering" and -logia (-λογία), "study of") is a significant field in modern medical diagnosis and medical research, concerned mainly with the causal study of disease, whether caused by pathogens or non-infectious physiological disorder.
