How to use this page
This page is a roadmap for understanding negative expressions and limitation expressions together.
It is not the main detailed guide for each expression. Use it first to see which expressions belong to each group and what order is easier for study.
For negative expressions, go to JLPT Negative Expressions That Learners Often Confuse.
For limitation expressions, go to JLPT Limitation Expressions That Learners Often Confuse.
Negative and limitation expressions show how far the denial goes
JLPT grammar often tests expressions such as 「わけではない」, 「ないことはない」, 「しかない」, 「ほかない」, and 「のみ」.
They may all be translated with “not” or “only,” but in Japanese they differ in whether the denial is partial, soft, strong, or limiting.
This page organizes related RJT articles so you can review negative and limitation expressions together.
Soft negative expressions
わけではない, ないことはない, and とは限らない
First, review expressions that avoid denying something too directly.
- Negative expressions such as 「わけではない」, 「とは限らない」, and 「ないことはない」
- The difference between 「ないことはない」 and 「わけではない」
- The difference between 「わけではない」 and 「とは限らない」
「わけではない」 softly corrects an assumption. 「ないことはない」 means that something is not completely impossible or not completely false, but the speaker is not strongly positive either.
Strong limitation
しかない, ほかない, and にほかならない
Next, study expressions that show there are very few options.
- The difference between 「しかない」 and 「ほかない」
- The difference between 「にほかならない」 and 「にすぎない」
- The difference between 「にすぎない」 and 「しかない」
「しかない」 and 「ほかない」 show that there is no other choice. 「にほかならない」 is a formal expression used for strong assertion.
Ways to express limitation
だけ and のみ
「だけ」 and 「のみ」 both express limitation, but they are used in different styles.
「だけ」 is common in both speech and writing. 「のみ」 is more common in written notices and formal contexts.
Feelings and actions that cannot be controlled
ずにはいられない and ないではいられない
Some grammar patterns include a negative form but actually express a strong feeling or action.
Both mean that the speaker cannot help doing something, but they differ in style and usage.
Strong denial and weak prediction
はずがない, わけがない, まい, and ないだろう
Negative expressions also connect to inference and judgment.
- The difference between 「はずがない」 and 「わけがない」
- The difference between 「まい」 and 「ないだろう」
- The difference between 「そうにない」 and 「そうもない」
「はずがない」 and 「わけがない」 show strong denial. 「ないだろう」 is a negative prediction. 「そうにない」 and 「そうもない」 show that something seems unlikely to happen.
Recommended study order
A good order for learning these expressions is:
- Learn soft negation with 「わけではない」 and 「ないことはない」
- Study strong limitation with 「しかない」 and 「ほかない」
- Compare spoken and written limitation with 「だけ」 and 「のみ」
- Notice the gap between form and meaning in 「ずにはいられない」
- Organize strong denial with 「はずがない」 and 「わけがない」
Related grammar guides
Negative and limitation expressions often appear together with inference and formal written expressions. Do not judge from one word only. Check how much of the sentence is being denied or limited.
