Vocabulary Mastery
How to learn vocabulary effectively
Learn the parts of speech
Knowing whether a word is a noun, verb, adjective, or adverb changes how you use it. Understanding grammatical function helps you build sentences correctly and remember the word in context.
Use example sentences
A word learned with an example sentence is remembered two to three times better than a word learned from a definition alone. Always read and re-read the example sentence, not just the definition.
Make your own sentences
The most powerful vocabulary technique: after reading a definition and example, write your own sentence using the word in a context that's personally relevant to you. This creates a strong memory hook.
Take it further
Definitions are the foundation.
Turn them into flashcards and use
spaced repetition to make the

Frequently Asked Questions
Can I define words from a specific field?
Yes — paste subject-specific vocabulary (medical, legal, scientific, literary, etc.) and the AI provides field-appropriate definitions. For ambiguous words, it uses context from the surrounding text to pick the right meaning.
Can it extract vocabulary from a passage automatically?
Yes — paste any paragraph or passage and the AI automatically identifies the key vocabulary worth defining. This saves time compared to manually selecting words to look up one by one.
How many words can I define at once?
The free tool handles up to 3,000 characters — typically 10-20 words or a short paragraph. Create a free Duetoday account to define vocabulary from longer texts and documents without limits.
Can I turn the definitions into flashcards?
In the full Duetoday app, you can automatically convert any vocabulary list into a flashcard deck with one click, then use spaced repetition to learn the words efficiently over time.
