Casual Speech Lesson 2

Master essential casual markers: だ, じゃん, って, んだ, and よね. Learn how to soften or emphasize your speech with friends.

Context

Casual Conversations

When speaking with close friends or family, using polite forms like 'desu' or 'masu' can sound distant or overly formal. In Japan, switching to casual speech is the key to building closer relationships.

Imagine you are at a cafe with a close friend. Instead of saying 'It is hot, isn't it?' using formal grammar, you might say 'Atsui jan?' (It's hot, right?). These small changes in your sentence endings make your Japanese sound natural and friendly.
Friend

きょう、あついよね?

今日、暑いよね?

It's hot today, isn't it?

You

ほんとうだね。あいすたべたいじゃん?

本当だね。アイス食べたいじゃん?

It really is. Don't you want to eat ice cream?

Explanation

Core Casual Markers

Casual speech relies on replacing formal endings with shorter, more expressive particles.

[Plain Form]+だ/じゃん/って/んだ/よね
  1. : The casual version of 'desu'. 2. じゃん: Used to seek agreement or point out something obvious (short for 'ja nai ka'). 3. って: Used to quote someone or define a topic. 4. んだ: Adds an explanatory tone, often used when giving a reason. 5. よね: Used to confirm shared knowledge or seek agreement.

Watch out

Casual speech is strictly for friends, family, or people younger than you. Using these forms with superiors or strangers is considered rude.
Examples

Seeing it in Action

Here are examples of these markers used in natural sentences.

これおいしいじゃん

This is delicious, isn't it?

これこれthisおいしいおいしいdeliciousじゃんじゃんisn't it

明日(あした)行く(いく)んだ

I'm going tomorrow (as an explanation).

明日あしたtomorrow行くいくto goんだんだexplanatory marker

それはいい【じゃん】!

Hint: The casual marker for 'isn't it?'

That's good, isn't it!

Usage

Register and Nuance

Knowing when to use these is just as important as knowing how to form them.

Polite vs Casual

暑いですね

Polite: Standard, safe for everyone.

あついですね

暑いよね

Casual: Friendly, seeking agreement.

あついよね

Which of these is appropriate for a conversation with your boss?

  • 明日、行くんだ。
  • 明日、行きます。

Always use polite forms (masu/desu) with superiors. '行くんだ' is too casual.

Deep dive

Deep Dive: The 'tte' particle

The particle 'tte' is extremely versatile in casual Japanese.

You will often hear 'tte' used as a shortened version of 'to iu' (called/saying). For example, 'Tanaka-tte dare?' means 'Who is this person called Tanaka?'. It is also used to repeat what someone else said: 'A: I'm tired. B: Tsukareta-tte? (You said you're tired?)'.
