Japanese Grammar – This is not an easy problem. 🇯🇵

この もんだい は かんたん____です。

Explanations:
In Japanese, a negative statement is often formed by using the word "じゃない" (janai) which means "is not" or "are not." When you want to negate an adjective or a noun, you attach "じゃない" to the appropriate form of the adjective or noun.

For the adjective かんたん (kantan), which means "easy," to form the negative you follow this structure:

1. Take the adjective: かんたん (kantan)
2. Add "じゃない" after it: かんたんじゃない (kantan janai)

This combined phrase means "is not easy."

Thus, when translating the sentence "This is not an easy problem." into Japanese, you get:
この もんだい は かんたんじゃないです。
(Kono mondai wa kantan janai desu.)

Other Information:
– です (desu) is a copula or linking verb in Japanese often used to make the sentence sound polite.
– "じゃない" can be used with both い-adjectives and な-adjectives to form negative sentences in a casual manner.
– For formal or written Japanese, you might sometimes see the negative form "ではありません" (dewa arimasen) being used instead of "じゃない."

Therefore, in the sentence, この もんだい は かんたんじゃないです。The "じゃない" clearly indicates that the adjective かんたん is negated.
