と — Natural and Automatic Conditional
This lesson covers the と conditional form, used when a condition inevitably or naturally leads to a result (e.g., 春になると、花が咲く – 'When spring comes, flowers bloom'). You'll practice forming sentences with と, understand its restrictions (cannot use with volition, requests, or commands), and compare it with other conditionals like たら, ば, and なら.
🎯 Goal: Use と to express conditions with automatic or natural results.
Lesson Content
Learning Goal
By the end of this lesson, you will be able to use と (to) to express conditions that lead to natural, automatic, or inevitable results. This is a key N4 grammar point for describing cause-and-effect relationships that are generally true.
Concept
と (to) connects two clauses:
- Clause A (condition) + と + Clause B (natural/automatic result)
The result in Clause B happens automatically whenever the condition in Clause A is met. It is not about personal will or intention—it describes facts, habits, or predictable outcomes.
Step-by-Step Breakdown
1. Structure
- Verb (dictionary form / ない-form) + と + Result
- い-adjective + と + Result (rare, but possible)
- Noun + だ → Noun + だと + Result
2. Meaning
- "When/if [condition], then [result] naturally happens."
- The result is automatic—it's not a choice or command.
3. Key Points
- The result clause cannot be a request, command, invitation, or expression of will (e.g., 〜てください, 〜ましょう, 〜たい).
- Use と for general truths, habits, or inevitable consequences.
Mini Examples
| Japanese | Romaji | English |
|---|---|---|
| 春になると、花が咲きます。 | Haru ni naru to, hana ga sakimasu. | When spring comes, flowers bloom. |
| ここを押すと、ドアが開きます。 | Koko o osu to, doa ga akimasu. | If you push here, the door opens. |
| 毎日勉強しないと、テストに合格しません。 | Mainichi benkyou shinai to, tesuto ni goukaku shimasen. | If you don't study every day, you won't pass the test. |
| あの道をまっすぐ行くと、駅があります。 | Ano michi o massugu iku to, eki ga arimasu. | If you go straight on that road, there's a station. |
Common Mistake
❌ 間違った例 (Wrong): 時間があると、映画を見ましょう。
(Jikan ga aru to, eiga o mimashou.)
→ This is wrong because the result is an invitation (ましょう). と cannot be used with willful expressions.
✅ 正しい例 (Correct): 時間があると、映画を見ます。
(Jikan ga aru to, eiga o mimasu.)
→ "When I have time, I watch a movie." (This describes a habit, not an invitation.)
Quick Practice
Fill in the blanks with the correct form + と.
-
このボタンを＿＿＿＿＿＿＿＿、電気がつきます。
(Kono botan o ______, denki ga tsukimasu.)
→ 押す (osu) — "If you press this button, the light turns on." -
雨が＿＿＿＿＿＿＿＿、試合は中止です。
(Ame ga ______, shiai wa chuushi desu.)
→ 降る (furu) — "If it rains, the game is canceled."
Summary and Next Step
と is your tool for describing automatic, natural results—like scientific facts, machine operations, or personal habits. Remember: no commands or invitations in the result clause.
Next step: Practice using と with い-adjectives and な-adjectives (e.g., 安いと、買います / 静かだと、勉強しやすいです). Then move on to ば (conditional) to compare nuance.
