にくい means hard to do. It is a JLPT N4 Japanese grammar pattern used to express the N4 idea of “difficult to do” in natural Japanese.
This grammar point often appears in conversation, written explanations, formal notices, and JLPT-style reading questions. If you want to express the N4 idea of “difficult to do” in natural Japanese, にくい is a useful pattern to learn after the N5 basics.
What does にくい mean?
Use にくい when you want to express the N4 idea of “difficult to do” in natural Japanese.
Natural translations include:
- difficult to do
- difficult to do
- difficult to do
The exact English translation changes with context. Focus on what the grammar point does in the sentence first, then choose the English phrase that sounds natural.
How to form にくい
Verb masu-stem + にくい
Examples of the pattern:
- Verb masu-stem + にくい
- Verb masu-stem
- にくい
Pay attention to the word form before the pattern. Many JLPT N4 mistakes happen because the meaning is understood, but the grammar is attached to the wrong form.
When is にくい used?
Use にくい in situations like:
- explaining a condition, reason, decision, comparison, or time relationship
- making a sentence more specific than a basic N5 pattern
- understanding natural Japanese in conversation or reading
Tone and register:
- neutral unless the grammar itself is marked as casual, humble, honorific, or formal
- Common in daily speech, textbook examples, and JLPT N4 reading questions
にくい example sentences
- この漢字は読みにくいです。 — This kanji is hard to read.
- このペンは使いにくいです。 — This pen is hard to use.
- この肉は食べにくいです。 — This meat is hard to eat.
- 彼の声は聞きにくいです。 — His voice is hard to hear.
- この道は歩きにくいです。 — This road is hard to walk on.
Read the Japanese sentence first, then check the English translation. Try to notice what the grammar point contributes: condition, timing, limitation, possibility, decision, politeness, contrast, or emphasis.
Nuance of にくい
The key nuance is difficult to do in a sentence-specific context.
This matters because にくい may look simple in English, but the Japanese form tells you whether the speaker is describing a time, a condition, a decision, a possibility, a contrast, or a social relationship.
For example:
- In context, にくい helps make the sentence more precise than a direct English translation.
- Compared with やすい, it has a different focus even when both patterns appear in similar sentences.
にくい vs やすい
Both {jp} and {similar} can appear in related sentences, but they are different.
にくい:
- is the target JLPT N4 pattern in this lesson
- carries the specific nuance explained above
やすい:
- is useful for comparison because learners often mix it up
- may use a different form, tone, or sentence focus
Quick contrast examples:
- Target pattern: この漢字は読みにくいです。 — This kanji is hard to read.
- Related pattern with やすい: compare the form and ask whether the sentence is about timing, condition, ability, decision, contrast, or politeness.
If you are unsure which one to use, identify the main job of the sentence before translating it into English.
Common mistakes with にくい
Watch out for these mistakes:
- Using it with the wrong verb, noun, or adjective form
- Confusing it with やすい because the English translation can look similar
- Translating it too literally instead of reading the whole sentence context
A good study habit is to write one short sentence and then change only the grammar point. This makes the difference between similar patterns easier to feel.
Is にくい on the JLPT?
Yes. にくい 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
For test preparation, do not only memorize the English gloss. Practice identifying the words around the grammar point, because JLPT questions often test structure and context together.
Practice questions for にくい
Try making your own sentences with these prompts:
- Write one sentence using the basic pattern.
- Change the sentence into polite or casual style if possible.
- Compare it with the related pattern from the comparison section.
Keep the sentences short at first. Once the form feels natural, add time words, places, reasons, or contrast to make the sentence more realistic.
