Transitions are words or phrases that cue the reader of a movement from one idea to the next. They occur within a paragraph and between them. Since ideas should be written as if they flow together in some kind of sensible manner, a transition act as a bridge between the writer's thoughts. If a writer does not use transitions, her writing will often feel jerky or unorganized. Many times the reader will have to pause and try to figure how one idea relates to another. This is a problem, as anytime the "flow" of the text is interrupted there is a danger that the reader will be lost completely.
