In Japanese, there are two main types of adjectives: i-adjectives and na-adjectives.

Key Differences:

1. Ending:

   • I-adjectives: These adjectives end with the sound "i" (い). For example, takai (高い) means "high."
   • Na-adjectives: These need the word "na" (な) before a noun. For example, shizuka (静か) means "quiet."

2. Changing Forms:

   • I-adjectives: They can change to show time or to say something is not true. For example, takakunai (高くない) means "not high."
   • Na-adjectives: They often use "desu" for polite speech. For example, shizuka desu (静かです) means "is quiet."

Knowing these differences is important for making sentences right in everyday Japanese!
