* To avoid monotony: Repeating the same transition phrase over and over can make writing sound repetitive and dull. Using a variety of transitions keeps the writing fresh and engaging.
* To create different relationships between ideas: Different transitions signal different relationships between ideas. For example, "however" signals a contrast, while "furthermore" signals an addition. Choosing the right transition helps to make the flow of ideas clear and logical.
* To emphasize particular points: Some transitions are stronger than others, and can be used to emphasize a particular point or argument. For example, "in fact" or "moreover" can strengthen a point, while "however" can introduce a counterargument.
* To match the tone and style of the writing: Different transitions can create different tones and styles. Formal writing often uses more sophisticated transitions, while casual writing might use simpler ones.
In essence, writers vary transitions to:
* Enhance readability: by avoiding redundancy and keeping the writing interesting.
* Clarify meaning: by accurately highlighting the relationship between ideas.
* Influence the reader: by emphasizing specific points and establishing the desired tone.
