In Japanese, the words you use for family members change depending on whose family you're talking about. This reflects a cultural concept called uchi-soto (内 Soto, uchi-soto), which translates to 'inside/outside'. Your own family is your 'in-group' (uchi), and everyone else's family is an 'out-group' (soto). When speaking about your own family to someone else, you use humble, plain terms. When speaking about someone else's family, you use polite, honorific terms.

This might feel strange at first, but it's a core part of showing respect. You elevate others by speaking of their family honorifically, while you lower your own family's status by using humble terms. Think of it as a form of social politeness built directly into the vocabulary.

Notice that for younger siblings, you simply add the suffix さん to the base word when referring to someone else's family. You can also use the polite 'soto' forms (like お母さん) to address your own family members directly, similar to how you'd call out "Mom!" in English.

When you address or refer to someone, you almost always attach a suffix to their name. It's considered rude to use someone's name by itself unless you are very close friends. The most common and versatile suffix is さん (san).

While さん is your go-to suffix, you'll hear a few others:

• くん (kun): Typically used for boys, teenage males, or by a superior to a junior male colleague. It's less formal than さん.

• ちゃん (chan): An endearing suffix used for young children, babies, and close female friends or family members. It implies a sense of cuteness and familiarity.

• 様 (sama): A very formal suffix used for customers, deities, or in formal writing. You'll see it in business emails but won't use it much in daily N5-level conversation.

Just like family, many common nouns for occupations and social roles are essential for basic conversation. You can often use these titles by themselves or with a person's name.

The word 先生 (sensei) is a broad term of respect for teachers, doctors, lawyers, or any master of a craft. It's polite to refer to your teacher simply as 先生. For other roles, you would typically use their name plus さん, like 「田中さんは会社員です。」 (Tanaka-san wa kaishain desu), meaning "Mr. Tanaka is a company employee."

Let's check your understanding of these key terms.

Mastering these terms will give you a solid foundation for talking about and to people in Japanese.
