Dictionary vs. Thesaurus: What’s the Difference?
They’re often used together, but they answer two different questions.
What a Dictionary Tells You
A dictionary explains what a word stands for, its part of speech, and how it’s typically used in a sentence.
What a Thesaurus Tells You
A thesaurus points you toward other words with a similar feel — handy when you already know what you want to say but not the best word for it.
This page brings both together in one place, so you don’t need to bounce between two different tools.
