The 50 Best Vocab Words for the ACT Essay

 

When taking the ACT essay section, students have 45 minutes to write a well-reasoned argumentative essay about a given prompt. The new ACT Essay prompts tend to be about “debate” topics — two sides of an issue are presented, with no obviously “right” side. Oftentimes, these subjects carry implications for broader issues such as freedom or morality. Test-takers are expected to convey some stance on the issue and support their argument with relevant facts and analysis.

 

In addition to some of the more obvious categories, like grammar and structure, students’ essays are also evaluated on their mastery of the English language. One way to demonstrate such mastery is through the correct usage of advanced vocabulary words. Below are 50 above-average vocabulary words sorted by the contexts in which they could most easily be worked into an ACT essay.
