Grammar Notes & Usage Tips
•Particle Pairing:** When using 同じ (おなじ) to compare two things, pair it with the particle と (to) to indicate what is being compared, like in "AとBは同じです" (A and B are the same).
•No Na-Form Needed:** Unlike most na-adjectives, 同じ doesn't require the な before a noun, so you can directly say "同じ人" (same person) instead of "同じな人."
•Expressing Similarity:** To say something is similar rather than identical, use the word よう (you) with に (ni), like in "同じように見える" (looks similar).
•Negative Form Tip:** To express "not the same," use "同じではない" (onaji de wa nai) or the casual form "同じじゃない" (onaji janai) to indicate differences.
•な-adjective: Uses な before nouns, conjugates like a noun
