In defining the concept of suicide there are certain difficulties. The question is whether is it just committed suicide or under suicide behavior may be included self-destructive behavior. Definition of suicide went from a strict refinement and separation from similar concepts to situation where thinking about the definition in the term is almost unnecessary.

This paper will cover in detail the history, definitions, etiology, intervention andidentify the suicidal person, key issues and motives for committing suicide. Mention will also be ways of suicide as women and men choose different means to commit suicide. According to research, women are attempt suicide more, and unlike men commit it.
