Since dictionaries use different systems for guide words, there's no single answer. Here's why:
* Some dictionaries use the first word on the page and the last word on the page. If the word "harvest" is somewhere in the middle of the page, the guide words would be the words at the beginning and end of the page.
* Other dictionaries use words that are alphabetically close to the target word. So, the guide words might be "harbinger" and "hat".
* Some dictionaries use a more condensed system, listing only the first few letters of each guide word. This might look like "harv" and "hat."
To find the correct guide words, you'll need to look at the specific dictionary you're using.
