In Japanese, the way you talk can change a lot depending on whether you are being polite or casual. This choice sets the mood for conversations and shows how close you are to the other person. Here are some important points to remember:

1. Words:

   • Polite: You use special endings like です (desu) and ます (masu) to sound polite. For example, "行きます" (ikimasu) means "go" in a polite way.
   • Casual: When you're with friends, you can just say "行く" (iku), which is a more relaxed way to say "go."

2. Showing Respect:

   • Polite: You add extra nice words to make the other person's actions seem more important. For example, "いらっしゃる" (irassharu) means "to go" in a respectful way.
   • Casual: You just use regular verbs without adding anything special.

3. Where and How You Speak:

   • Polite: You use this way of speaking when you're in formal situations or talking to someone you don't know well.
   • Casual: This way is for chatting with friends, family, or people your age.

Knowing these differences is super important for getting along with others!
