Start by clicking the Start a New List button on the Vocabulary List home page.
Paste text from any source into the text box — say, an article you are reading, or even a whole book (you can paste up to 100 pages). Press the Next Step button.
We'll instantly analyze the text and grab all the relevant vocabulary words from the text. These are words that we determine are necessary to fully understand the meaning of the text.
We'll highlight the top 10, but you can include (or exclude) as many as you like.
Optionally, click the gear icon at the top right to sort or filter the list.
Click the "Edit" button next to the word to change the definition, example sentence or to add notes.
Click the Learn These Words button to start a practice session on the list. Or, if you are a teacher, click the Assign These Words button then click on the Assignments tab to assign Practice, a Spelling Bee, a Quiz, or a Vocabulary Jam to your class.
