Grammar Notes & Usage Tips

•Basic Conjugation**: 赤い (あかい) is an i-adjective, so when you want to say something "is red," use it directly before the noun, like 赤い車 (あかいくるま) for "red car."

•Negative Form**: To say something is "not red," change the ending to 赤くない (あかくない), as in 赤くないシャツ (あかくないシャツ) for "not a red shirt."

•Past Tense**: For past tense, say 赤かった (あかかった) to mean "was red," like in 赤かった空 (あかかったそら) for "the sky was red."

•Using Particles**: When describing a noun with 赤い, you don't need a particle between the adjective and the noun; simply place 赤い directly in front, such as in 赤いリンゴ (あかいリンゴ) for "red apple."

•い-adjective: Conjugates by changing the い ending
