Grammar Notes & Usage Tips
•Na-Adjective Basics**: As a na-adjective, 簡単 (かんたん) needs a "な" when directly modifying a noun, like in 簡単な問題 (かんたんなもんだい) meaning "a simple problem."
•Predicative Use**: When using 簡単 at the end of a sentence to describe something, you don't need the "な." Just say, "このテストは簡単です" (このテストはかんたんです) for "This test is simple."
•Negative Form**: To express "not simple," use the negative form 簡単じゃない (かんたんじゃない) or 簡単ではない (かんたんではない), which both mean "not simple."
•Past Tense**: To talk about something that was simple, convert it to the past tense by changing it to 簡単だった (かんたんだった), like in "その仕事は簡単だった" (そのしごとはかんたんだった), meaning "That job was simple."
•な-adjective: Uses な before nouns, conjugates like a noun
