Grammar Notes & Usage Tips
•Na-adjective Usage**: Remember that 無理 (むり) is a na-adjective, so when you want to use it to describe a noun, you attach な, making it 無理な. For example, "an impossible task" is 無理な仕事 (むりなしごと).
•Particle Pairing**: When using 無理 in a sentence, it often pairs with the particle です to express "it's impossible" or "it's unreasonable," as in それは無理です (それはむりです).
•Conjugation Tip**: To say something is "not impossible" or "not unreasonable," just add じゃない to make it 無理じゃない, which can be used in casual speech as in それは無理じゃない (That's not impossible).
•Common Expressions**: A handy phrase is 無理しないで (むりしないで), which means "don't overdo it" or "take it easy," and is often used to show concern for someone's well-being.
•な-adjective: Uses な before nouns, conjugates like a noun
