だって

だって means because; but; after all; even; too. It is a JLPT N2 Japanese grammar pattern used to express that a colloquial way to give a reason, excuse, or to say ‘even X too’.

This grammar point often appears in essays, formal writing, conversations, and JLPT N2 reading passages. If you want to express that a colloquial way to give a reason, excuse, or to say ‘even X too’, だって is a useful pattern to learn because it adds natural precision to your Japanese.

What does だって mean?

Use だって when you want to express that a colloquial way to give a reason, excuse, or to say ‘even X too’.

Natural translations include:

• because; but; after all; even; too

The best translation depends on the sentence. Try to notice the writer’s or speaker’s purpose first, then choose the English phrase that fits that context.

How to form だって

だって + Sentence (at start) / Noun + だって

Examples of the pattern:

• だって、疲れたんだもん
• 私だってできる

The form before the grammar point matters. In JLPT questions, the wrong answer choices often use a similar meaning but attach it to the wrong type of word.

When is だって used?

Use だって in situations like:

• giving a reason, making an excuse, or saying ‘even’
• expressing personal reactions, reasoning, or observations
• connecting ideas in formal and informal contexts

Tone and register:

• colloquial; common in daily speech, complaints, and excuses
• Common in test questions, essays, daily conversation, and JLPT N2 reading

だって example sentences

• だって、誰も教えてくれなかったんだ。
• 私だって行きたい。
• だって、それは無理だよ。
• 子供だってできる簡単な問題だ。
• だって、時間がなかったんだから。

After reading each sentence, ask what job だって is doing: a colloquial way to give a reason, excuse, or to say ‘even X too’. That makes the nuance easier to remember than a one-word translation.

Nuance of だって

The key nuance is a colloquial way to give a reason, excuse, or to say ‘even X too’.

This matters because learners often translate advanced grammar too literally. A pattern may look simple, but it can signal the writer’s attitude, the scope of a rule, or the relationship between two ideas.

For example:

• In context, it carries a specific, nuanced meaning that a simpler pattern would not convey.
• Compared with でも, it carries a different weight and implication.

だって vs でも

Both だって and でも can express related ideas, but they are different.

だって:

• a colloquial way to give a reason, excuse, or to say ‘even X too’

でも:

• but; however; even (more neutral)

Quick contrast examples:

• だって、知らなかったんだ。
• でも、知らなかったんだ。

If both translations seem possible, check the tone. Is the sentence casual, formal, written, explanatory, or emotional? The tone often tells you which grammar point is natural.

Common mistakes with だって

Watch out for these mistakes:

• Translating it too literally without understanding the nuance
• Using it in contexts where the situation doesn’t match the grammar’s core meaning
• Confusing it with similar-looking but different grammar patterns

A helpful practice method is to write one sentence with だって, then rewrite it with でも. If the meaning or tone changes, explain that difference in your own words.

Is だって on the JLPT?

Yes. だって is commonly taught as JLPT N2 grammar.

That means learners should be able to:

• recognize it in reading
• understand its nuance in context
• use it in simple original sentences

For test preparation, study the grammar point in full sentences. JLPT questions often test whether you understand the surrounding context, not just the dictionary meaning.

Practice questions for だって

Try making your own sentences with these prompts:

• Use だって in a sentence about a personal experience or observation.
• Write a sentence where the nuance of だって is necessary.
• Compare だって with でも in your own example.

Keep your first sentences simple. Once the structure feels natural, add more context so the nuance becomes clear.

1. First, make sure you can form だって without looking at the pattern chart.
2. Next, compare it with でも. These patterns are close enough that choosing between them helps you understand the nuance.
