JLPT level: N4 · Updated: 2026-05-17 · Canonical: https://hane-app.com/blog/n4-tara/

**たら** means **if; when; after**. It is a **JLPT N4** Japanese grammar pattern used to express this idea in natural Japanese.

This English meaning is written independently from the source list so it answers the learner question directly: what does **たら** mean and when should you use it?

## What does たら mean?

Use **たら** when you want to express **if; when; after** in a Japanese sentence.

Natural translations include:
- if; when; after
- if
- when

## How to form たら

Plain past form + ら

Examples of the pattern:
- Plain past form + ら
- たら
- related form: なら

## When is たら used?

Use **たら** in situations like:
- reading or writing JLPT N4-level sentences
- making a sentence more precise than a basic N5 pattern
- recognizing natural grammar in conversation or short passages

Tone and register:
- usually neutral unless the pattern itself is casual, humble, honorific, or written
- common in JLPT N4 grammar study and everyday examples

## たら example sentences

- 雨が降ったら、家にいます。 — If it rains, I will stay home.
- 日本に着いたら、電話してください。 — Call me when you arrive in Japan.
- 宿題が終わったら、遊びましょう。 — After you finish your homework, let’s play.
- 安かったら、買います。 — If it is cheap, I will buy it.
- 時間があったら、手伝ってください。 — If you have time, please help.

## Nuance of たら

The key nuance is **if; when; after in context**, not a word-for-word English replacement.

This matters because **たら** often changes the relationship between actions, people, time, or evidence in the sentence. Read the whole sentence before choosing the English translation.

## たら vs なら

Both patterns can appear in related sentences, but they do different jobs.

**たら**:
- is the target JLPT N4 pattern in this lesson
- focuses on **if; when; after**

**なら**:
- is useful for comparison because learners often confuse nearby forms
- may change the tone, evidence, direction, or relationship in the sentence

Quick contrast examples:
- Target pattern: 雨が降ったら、家にいます。 — If it rains, I will stay home.
- Related pattern with **なら**: compare what changes in evidence, timing, direction, or politeness.

## Common mistakes with たら

Watch out for these mistakes:
- Copying a dictionary gloss without checking the sentence context
- Using the wrong verb, adjective, or noun form
- Confusing **たら** with **なら** because the English can sound similar

## Is たら on the JLPT?

Yes. **たら** is connected to **JLPT N4** grammar in this blog.

That means learners should be able to:
- recognize it in reading
- understand its nuance in context
- use it in simple original sentences

## Practice questions for たら

Try making your own sentences with these prompts:
- Write one short sentence using the basic structure.
- Replace the subject, time, or object and keep the same grammar point.
- Compare your sentence with the related pattern above.

## Learning path for たら

Use **たら** as part of your **JLPT N4** condition, contrast, and concession grammar toolkit. First decide whether **たら** presents a real condition, a general rule, a one-time situation, or an “even if” contrast. Then practice changing the second half of the sentence, because N4 conditionals often change nuance through the result clause.

A good review order is: first make one short sentence with **たら**, then compare it with [ば](/blog/n4-ba/), and finally add [なら](/blog/n4-nara/) or [と](/blog/n4-to-conditional/) to see how the nuance changes.

For practice, write one sentence that uses **たら** in its most literal meaning, one sentence that changes the subject or time expression, and one sentence that contrasts it with one of the related patterns below.
