Notes & Nuances

📌 Important Points

Conjugation
Attach 〜にくい to the ます-stem of the verb. Example: 食べます (tabemasu) -> 食べ (tabe) -> 食べにくい (tabenikui).
Example: 使いにくい (tsukainikui – hard to use)
Opposite meaning
The opposite of 〜にくい is 〜やすい (yasui), which means “easy to do” or “has a tendency to easily do”.
Example: 食べやすい (tabeyasui – easy to eat)

⚠️ Common Mistakes

❌ Attaching to the plain form or -te form.
✅ Always use the ます-stem.
Incorrect: 読むにくい (yomunikui), 読んでにくい (yonde nikui). Correct: 読みにくい (yominikui).
❌ Confusing with 〜のが難しい (~no ga muzukashii).
✅ 〜にくい describes an inherent difficulty or characteristic, while 〜のが難しい is a more general statement about an action being difficult.
While “運転するのが難しい” (Unten suru no ga muzukashii – Driving is difficult) is a general statement, “この車は運転しにくい” (Kono kuruma wa unten shinikui – This car is hard to drive) implies a difficulty related to the car’s characteristics.

🏛️ Cultural Context

Politeness Level: Neutral. Can be used in most situations without being overly polite or informal.
Social Situations: Used widely in daily life when describing objects, tools, environments, or tasks.
Regional Variations: This pattern is standard across Japan.

🔍 Subtle Differences

〜にくい vs 〜づらい (~zurai)
〜にくい often describes objective physical or external difficulty/inconvenience. 〜づらい can also describe objective difficulty but often implies more subjective difficulty, discomfort, or emotional reluctance.
When to use: Use 〜にくい for things that are physically hard to do or inherently inconvenient. Use 〜づらい when there’s a stronger sense of personal difficulty, discomfort, or emotional resistance, although there is overlap, especially in spoken language.

📝 Conjugation Notes

Always attach 〜にくい to the ます-stem of the verb. The 〜にくい part behaves like an i-adjective (e.g., 読みにくいです, 読みにくくないです, 読みにくかったです, 読みにくくなかったです).

🔊 Pronunciation Tips

Ensure the final vowel sound of the ます-stem blends smoothly into “ni”.

🧠 Memory Tips

Associate にくい (nikui) with “nasty/difficult” to remember the “difficult” meaning. Compare it directly with its opposite, 〜やすい (yasui – easy).
