Grammar Notes & Usage Tips

Basic Usage**: 黒い (くろい) is an i-adjective, so it directly modifies nouns, as in 黒い猫 (くろいねこ), meaning "a black cat." Just like in English, it comes before the noun.
Negative Form**: To say something is "not black," change the ending to くない, making it 黒くない (くろくない). For example, このシャツは黒くない (このしゃつはくろくない) means "This shirt is not black."
Past Tense**: To express that something was black in the past, use the past tense form 黒かった (くろかった). For example, 昨日見た猫は黒かった (きのうみたねこはくろかった) translates to "The cat I saw yesterday was black."
Particle Pairing**: When using 黒い in a sentence, the particle が or は can often follow the noun to indicate the subject, as in 猫が黒い (ねこがくろい) meaning "The cat is black," or 猫は黒い (ねこはくろい) for emphasis or contrast.
