- Strengthen your arguments: By directly linking evidence to your claims, you create more persuasive and credible arguments.
- Showcase vocabulary range: Using this phrase demonstrates your grasp of sophisticated vocabulary.
- Improve coherence and cohesion: It acts as a signpost, guiding the reader or listener through your arguments in a logical and structured way.
