Excellent question, Vireak! You have to look at the context! In "incorrect", it means "not". But in "include" or "inside", it refers to position. That is why looking at the whole sentence is so important! psychology

Always try to guess first! Guessing helps build strong connections in your brain. Once you have a guess, THEN check the dictionary to confirm. You will remember the word much better this way! menu_book

Brilliant observation! The root "dict" comes from Latin and means "to speak" or "to say". So a 'dictionary' tells you how to say words, and to 'predict' means to say what will happen before it does! record_voice_over
