Introductions guide the reader and establish the main point, while conclusions provide closure and summarize the key points.
When looking at introductions and conclusions in writing, it's important to distinguish their purposes. Introductions steer the reader in the direction that the rest of the piece is going, introduce the main point of the writing, and use devices to catch the reader's interest. Conclusions bring the writing to a logical end, may include transitions like 'in summary,' and summarize the central points discussed.
