To contrast two ideas, a writer would typically use the transition "although." This transition indicates a contrast between the two ideas presented in the text. Here's how it works:
1. "Although" introduces a contrasting idea that goes against the first idea presented. It sets up a comparison between the two ideas to show their differences or opposing nature.
2. For example, in a sentence like "Although she studied hard, she didn't perform well on the test," the use of "although" highlights the contrast between studying hard and not performing well, emphasizing the difference between effort and outcome.
3. This transition helps to create a clear distinction between the ideas being discussed, allowing the reader to understand the contrasting elements within the text.
So, when looking to contrast two ideas in writing, the transition "although" would be the most suitable choice.
