A transition is a word or phrase that unifies ideas by signaling a relationship between the ideas.
Explanation:
A speech can be classified into four main parts:
i) Introduction
ii) Body
iii) Transitions
iv) Conclusion
Transition refers to the words, phrases or paragraphs to move from the introduction part of the speech to the body. In simple, transition means moving from one point to the next.
A word or phrase is used throughout the speech to link the parts of the speech together. Transition helps the speaker to move smoothly and clearly from the intro to the body. It also helps in exiting from one part of the speech and moving to conclusion.
