Grammar Notes & Usage Tips
•Na-Adjective Conjugation**: As a na-adjective, 急 (きゅう) needs "な" when directly modifying a noun, like in 急な予定 (きゅうなよてい) meaning "urgent plans." Remember, you leave out the "な" when 急 is used as a predicate adjective, e.g., "予定が急です" (よていがきゅうです) meaning "The plans are urgent."
•Common Particle Pairing**: When expressing urgency or a sudden situation, 急 is often paired with the particle に, as in 急に (きゅうに), to mean "suddenly" or "abruptly," like in 急に雨が降り出した (きゅうにあめがふりだした) – "It suddenly started to rain."
•Special Usage Tip**: Don't confuse 急 (きゅう) with the i-adjective 急い (いそい) which is the stem of 急ぐ (いそぐ), meaning "to hurry." Remember 急 is more about the quality or nature of being urgent, while 急ぐ is the action of hurrying.
•Avoiding Common Mistakes**: When using 急 to describe something steep, like a slope, it's often used in phrases like 急な坂 (きゅうなさか) meaning "steep slope" or 急な階段 (きゅうなかいだん) for "steep stairs."
•な-adjective: Uses な before nouns, conjugates like a noun
