Grammar Notes & Usage Tips

•Placement Tip**: In Japanese, adjectives like 古い (ふるい) typically come before the noun they modify, so you'd say 古い本 (ふるいほん) for "an old book."

•Conjugation Reminder**: Being an i-adjective, 古い (ふるい) follows regular conjugation patterns: for example, the negative form is 古くない (ふるくない) meaning "not old."

•Particle Pointers**: If you're describing something as old, you can use the particle が to emphasize it, like 古い車がある (ふるいくるまがある) for "there is an old car."

•Context Clarification**: Remember, 古い (ふるい) is used for objects, buildings, or concepts, not people; for "old" in reference to age, use 年老いた (としおいた) instead.

•い-adjective: Conjugates by changing the い ending
