“〜tewa vs 〜naide”: The Core Difference in Negative Connection [JLPT N4]
Content by NTJ Kuma · Nihongo to Japan editorial team · Updated July 27, 2026
「遅刻しては困る」 vs 「予習しないで授業に出る」 — “doing it is bad” vs “without doing it.”
「宿題をしては遊ぶ」 vs 「宿題をしないで遊ぶ」 — a few letters, opposite meanings
「宿題をしては遊ぶ」 (keeps playing the moment homework's done → bad) vs 「宿題をしないで遊ぶ」 (plays without doing homework) — a few letters apart, nearly opposite meanings. These negative/conditional connectors get mixed up: 〜ては = “(if/always) doing ~ leads to (a bad result)”; 〜ないで = “without doing ~/not doing ~.” This guide separates the pair.
Core: ては (do → bad) vs ないで (not do / without)
- 〜ては = doing ~ leads to ~ (usually a bad result/repetition): 毎日遅刻しては、信用をなくす (always being late loses you trust). Also repetition (飲んでは歌い = drinking and singing).
- 〜ないで = without doing ~/not doing ~ (then something): 朝ごはんを食べないで、出かけた (went out without eating breakfast).
One is “did (leading to ~),” the other is “didn't/without.”
How to Connect
| Form | Use | Example |
|---|---|---|
| verb て-form + は | doing ~ leads to ~ (bad/repeated) | 遅刻しては |
| verb ない-form + で | without doing ~/not doing | 食べないで |
| 〜なくて | because ~ not (cause) | 分からなくて困る (it's a problem that I don't understand) |
Example sentences
- こんなに毎日遅刻しては、上司に怒られるよ。(Being late every day like this, you'll get scolded.) — do → bad
- 予習しないで授業に出た。(I went to class without preparing.) — without doing
- 傘を持たないで外出したら、雨に降られた。(I went out without an umbrella and got rained on.) — without
- 泣いては笑い、忙しい赤ちゃんだ。(Crying then laughing — a busy baby.) — repetition
- 宿題をしないで、ゲームばかりしている。(Not doing homework, just gaming.) — not doing (then)
⚠️ Common mistakes to avoid
① ては usually leads to a negative result. 「〜ては困る・だめだ・いけない」 (doing ~ won't do). It's not plain “after doing,” but carries a “this can't go on” judgment.
② 「ないで」 vs 「なくて」. 「〜ないで」 = without doing an action (食べないで寝た); 「〜なくて」 = because ~ not (cause: 来なくて心配した). For an accompanying state use ないで, for a cause use なくて.
③ 「ないで」 also makes requests. 「〜ないでください」 = please don't ~ (心配しないでください) — one of its most common uses.
🔄 Compare: ては/ないで/なくて
| Form | Nuance | Example |
|---|---|---|
| 〜ては | doing ~ leads to ~ (bad/repeated) | 遅刻しては困る (it'd be a problem if you were late) |
| 〜ないで | without/not doing (state, request) | 食べないで出た (left without eating) |
| 〜なくて | because ~ not (cause) | 来なくて困った (it was a problem that they didn't come) |
💡 The one thing to remember
These two are easily confused; hold the core contrast: 〜ては = “(always/if) doing ~ leads to something bad” (often + 困る・だめ); 〜ないで = “without doing ~/not doing ~” (also the request 「〜ないでください」). One line: ては is “doing it is bad,” ないで is “not doing/don't.” One more trap — the causal 「〜なくて」 (来なくて困った) shouldn't be confused with ないで.
❓ Questions you might have
Q: 「食べないで」 vs 「食べなくて」?
「食べないで」 = without eating/in an un-eaten state (朝ごはんを食べないで出かけた = went out without breakfast); 「食べなくて」 = because ~ doesn't/didn't eat (cause) (子供が野菜を食べなくて困る = troubled that the kid won't eat veggies). Accompanying state → ないで, cause → なくて.
Q: Does 「〜ては」 always mean a bad result?
Mostly (〜ては困る・いけない). Its core is “going on doing ~ leads to ~ (usually bad).” But the repetition use (泣いては笑い = crying then laughing) is a neutral “alternating repetition,” with no good/bad. Check whether a judgment or another repeated action follows.

Answer Explanations
1. (B) ないで ── 「予習しないで」(in the state of not preparing), 「授業に出る」(going to class) = doing one thing without the precondition action → ないで.
2. (A) ないで ──「宿題をしないで遊んではいけない」(you mustn't play without doing homework) = doing B in the state of "not doing A" → ないで. (B) なくて leans toward cause, (C) ては is "if you do 〜 it's bad," (D) たら is a condition.
3. (A) ては ── 「こんなに遅刻しては」(if you're late this much), 「困る」(it's a problem) = te-form + は + a negative evaluation = a typical use of ては (if you do 〜, it's bad).
4. (B) ないで ──「傘を持たないで外出した」(went out without taking an umbrella) = doing another action in the state of not carrying something → ないで (most natural colloquially). (D) ずに is its written synonym form; (A) ては / (C) なくて don't fit this context.
5. (B) ── ては = the condition "if you do 〜 (it's bad)" (usually followed by prohibition / warning); ないで = "doing another thing in the state of not doing 〜" (describing a situation where the precondition action is omitted).
