How do I use the structure niku to indicate difficulty?

What Is the Structure niku?

The structure niku (～にくい) is a Japanese grammatical pattern attached to the stem of a verb to indicate that something is “difficult to do.” It is commonly used in both spoken and written Japanese to express that an action is hard to perform, either physically or mentally.

How to Form niku

To use this structure, simply take the masu-stem (the base form of a verb before you add ます) and add にくい:

• Verb (masu-stem) + にくい

For example:

• 読む (yomu – to read) → 読み (yomi) + にくい = 読みにくい (yomi-nikui) = hard to read
• 使う (tsukau – to use) → 使い (tsukai) + にくい = 使いにくい (tsukai-nikui) = hard to use
• 分かる (wakaru – to understand) → 分かり (wakari) + にくい = 分かりにくい (wakari-nikui) = hard to understand

Common Uses of niku in Everyday Japanese

The niku structure is highly versatile and can be used in a variety of contexts. Here are some examples of how it might appear in daily conversations:

• このペンは書きにくいです。
  This pen is hard to write with.
• 彼の話は聞きにくい。
  It’s hard to listen to him (perhaps due to the way he speaks).
• このドアは開けにくい。
  This door is hard to open.

Notice that niku can refer to both physical and abstract difficulties.

Difference Between niku and yasui

It’s useful to remember that niku is the opposite of yasui (～やすい), which is used to express that something is “easy to do.” For example, 食べやすい (tabe-yasui) means “easy to eat,” while 食べにくい (tabe-nikui) means “hard to eat.”

Tips for Using niku Correctly

• Use the masu-stem: Always attach にくい to the verb’s masu-stem, not the dictionary (plain) form.
• Don’t confuse with negative forms: にくい does not mean “not to do”; it specifically relates to difficulty.
• Can be used in both formal and informal situations: Add です (desu) at the end to make your sentence more polite.
