Why VitaminWords

Learn words that actually stick

Every word is anchored to a root you already half-know — so new vocabulary feels familiar, not memorized.

🌱

Roots first

Each session opens with the Greek & Latin roots behind the words, so you can decode new words on sight.

📖

Rich study cards

Pronunciation, plain-language definitions, extra examples, synonyms & opposites — plus audio and a flashcard mode.

🎯

Four ways to test

Choose the word, complete the sentence, match meanings, and recall from memory — score 80% to advance.

🔒

Guided progression

Sessions unlock as you pass, with a chapter final after each unit and a 100-question course final.
