  • Picture a big box or a bag full of different words, each word like a colorful ball you can pick anytime
  • It feels like having many tools in your language toolbox to build sentences and ideas easily
  • Sounds like "vo-CAB-you-lary" → imagine a taxi (cab) full of words driving around to help you speak
  • Remember learning new words in school or from books, adding them to your personal word collection
  • NOT like "dictionary" (a book with words), vocabulary is the words INSIDE your mind or what you use
  • NOT like "sentence" (a group of words), vocabulary is the single words you know before making sentences
