We don’t waste your time. We start by looking at books, periodicals, and other material that cumulatively contain over 3.5 billion words (and growing). From this corpus, we pull out the most essential English vocabulary words, the words that you need to succeed in an academic or business environment. This analysis serves as the basis for our learning platform.
Vocabulary.com uses a proprietary technology that we call Adaptive Vocabulary Instruction (AVI). Unlike traditional learning systems, we don’t rely on a series of time-consuming and boring assessments. Instead, everything you do on the site adds to our AVI model. It’s like you have a personal trainer in the room, monitoring your work and suggesting new words and exercises to challenge you on your level. Because of this, you don’t waste your time learning words that are too easy or too hard.
Finally, we analyze your achievements, and reinforce your skills by reintroducing words at various times to make sure that you are retaining the words you originally learned.
At the heart of Vocabulary.com is the more than 178,000 vocabulary questions that we designed to evaluate and teach vocabulary words. Each question tests a particular meaning of a word, provides helpful hints, and is followed by an explanation of the correct answer. Many studies have shown that the best way to learn is through multiple exposures to a word, with challenging questions that make you think. That’s what we provide.
We use our own adaptive learning system to ensure that you get the right question at the right time. We build a model of your vocabulary and abilities as you answer each question, and then serve you up with questions that are not too hard and not too easy. From the results of these questions, we determine what words to focus on in your personalized learning program.
As you answer questions, we begin to compile a list of words to learn. If you get a question wrong or choose to use a hint, the word is added to the list. Once we add a word to this list, we keep working with you until you’ve mastered that word. You can see your list by visiting the My Progress / Words I'm Learning section.
If you’re having trouble with a question, we will sometimes provide a hint to help you along. Depending on the word, you can use your hint to eliminate a choice, to see sentence examples, or to see definitions of the word. If you get a question wrong, we provide you with a friendly Vocabulary.com description of the word. Read it! It’s designed to help you remember the word.
If you answer enough questions correctly on a word that you’re learning, you’ve mastered it. You can see the progress on one of the words you’re learning in the small bar graph next to the word. Once you’ve mastered a word, the bar turns gold.
On the upper right hand corner of each question is a question category and a point value. There are four question categories:
As you answer questions correctly and learn words, you earn points. And as you earn more points, you are assigned a badge that represents your level. You start as a “novice,” and then as you hit different point goals, you’ll earn new badges.
You can also earn extra badges based on various achievements, such as answering 5 questions correctly in a row, or acing a round. Click on My Progress to see a list of available achievements and levels.
You can find out more about how you’re doing by visiting the My Progress section. From there you’ll see charts on overall progress, as well as progress on any individual word.
We made an exhaustive review of the dictionaries out there, and we came to a not-so-startling conclusion. Current dictionary definitions can be difficult to understand and not much fun to read. This is fine if you’re looking up a word for reference, but if you’re actually trying to learn how a word is used in the real world and to make it part of your vocabulary, the typical dictionary definition is not going to do it.
Our dictionary is different. Most vocabulary words include a short blurb that describes what the word means and how the word is used. These blurbs are easy to understand and fun to read. If there’s an entertaining story about the word, we include it. If the word can be confused with another, we include that information as well. The point is to help you learn and remember the words you look up without having to look it up a hundred times.
Our search box is smart. So smart that it predicts what you’re looking up as you type. Try it. You’ll see that as you type, we’re making our best guess as to what word you’re looking for. If you see your word in one of the first five choices, you can click on it to see the word page, or if your word is number one, we’ll choose it for you.
We’ll help you out. For all the most confusing English words, we’ve provided articles that describe the difference. So if you look up affect, you’ll see both a short blurb describing the word as well as a longer discussion of how it differs from effect.
Each word has usage examples from our corpus of over 175 million sentences. You’ll see how words are used in edited language by some of the best writers in the world, from periodicals such as The New York Times, Scientific American, and from great works of fiction by writers as diverse as T. S. Elliot and Upton Sinclair. Seeing a word in context is a great way to understand how it’s used in the wild.
One of the best features of Vocabulary.com is that you can easily make and share Vocabulary lists. Create a Vocabulary List quickly from assigned words, grab words from any text, or generate a list from the Advanced Search. Then, you can master all the words on your list, or practice them for an upcoming quiz. You can also easily add notes and example sentences to your words so that you can jog your memory and see them in context while your are learning.
