Antonyms are really helpful when you’re trying to learn Japanese grammar! Here’s why: 1. **Understanding Meaning**: Knowing opposites can help you understand words better. For example, if you learn the word "大きい" (ookii - big), knowing "小さい" (chiisai - small) right away gives you a clearer idea of what these words mean. 2. **Pairing Words**: Using word pairs like "明るい" (akarui - bright) and "暗い" (kurai - dark) can help you learn new words quickly. Seeing them next to each other shows the differences and helps you remember them better. 3. **Building Sentences**: Learning antonyms helps you make more interesting sentences. For example: "彼は高いですが、彼女は低いです" (Kare wa takai desu ga, Kanojo wa hikui desu - He is tall, but she is short). In short, antonyms make your learning easier and a lot more fun!
