Guide words are the words at the top of each dictionary page that tell you the first and last entries on that page.
To find the guide word for "harvest," you'll need to actually look in a dictionary. It's impossible to know the guide word without knowing which dictionary you're using, as different dictionaries have different organization and page layouts.
Here's how to find it:
1. Open your dictionary: Look for the section where "harvest" would be located (likely alphabetically somewhere between "harbor" and "hat").
2. Find the page: Look for the page that contains the word "harvest".
3. Look at the top of the page: The guide words will be at the top of the page, usually near the top-left and top-right corners.
