Grammar Notes & Usage Tips
•Conjugation Tip:** As an i-adjective, 青い (あおい) follows regular i-adjective conjugation patterns, so for past tense, change it to 青かった (あおかった) to say something "was blue."
•Negative Form:** To express "not blue," simply drop the final い and add くない, making it 青くない (あおくない).
•Particle Usage:** When using 青い to describe a noun, place it directly before the noun, like in 青い空 (あおいそら) for "blue sky."
•Common Mix-Up:** Remember that 青い can also describe things that are green in English, like 青いりんご (あおいりんご), which refers to an "unripe green apple."
