About に難くない

にかたくない is a formal grammar pattern that uses a different version of the い-Adjective (むずか)しい 'difficult', (かた)い, which has the same meaning. This adjective will be used in the negative, in order to indicate that something is 'not difficult'. The case-marking particle に at the beginning is limited to following verbs that indicate thinking or conjecture.

  • 子供(こども)()くした(おや)たちの気持(きも)ちは理解(りかい)(かた)くない
    It is not difficult to understand the feelings of parents who have lost their children.
This structure will only appear with quite a limited number of verbs, with 想像(そうぞう) 'to imagine', 予想(よそう) 'to predict', (さっ)する 'to infer' or 'to sense', 理解(りかい) 'to understand', and 推測(すいそく) 'to guess' making up the majority of them.
Fun Fact
Many words have alternative forms that will be described as (A) の(あらた)まった表現(ひょうげん) 'the reformed version of (A)' in Japanese dictionaries. Although the standard meaning of the る-Verb (あらた)まる is 'to redo', it can also often be 'to reform' in the sense of making something ceremonious or formal. (A) will usually be the far more common or everyday version of a word, such as with (むずか)しい in the case of this grammar point.
