Think about something strange and unexplainable in your life. Maybe you get a headache right before it rains, or maybe you think your favorite sports team wins when you wear a certain color.

• Defining the term “hypothesis” 
• Providing hypothesis examples 
• Giving you tips for how to write your own hypothesis

However, there are some measures you can take to have a better chance of raising your GPA quickly and effectively. In this article, I'll give you different strategies that may help you raise your GPA even if you don't have much time left in high school.

One of the words that comes up most commonly in various types of writing, from fiction to academic writing, is the word “said.” Any time a writer is referencing the words or thoughts expressed by another person, whether that be thoughts expressed verbally or in writing, an appropriate way to introduce--or attribute--that person’s thoughts is with the phrase “said.” 

But if you’re incorporating a lot of quotations in your writing, you might find yourself repeating  the word “said” a lot. Repeating the same phrase in a piece of writing can start to feel monotonous, which is why incorporating synonyms or an oft-used word or phrase can make your writing more interesting and accurate. But here’s some good news: there are tons of other words for “said” out there for you to use! 

To help you build a repertoire of words to replace “said,” we’re going to do the following in this article: 

• Explain the importance of using word variety and avoiding repetition of the same word in your writing
• Explain when to use “said” and when not to use “said” 
• Provide a comprehensive list of alternative words for “said,” organized into categories based on emotion and intention
