のに

although, despite, even though, and yet

Verb or い-Adjective + のに

のに is used to express that the outcome in the second part of the sentence is contrary to what would normally be expected from the first part. It often carries a nuance of surprise, regret, or dissatisfaction.

Verb informal

The informal form of a verb is used before のに.

Even though I ate, I am hungry.

Although I studied, the test was difficult.

い-Adjective informal

い-Adjectives in their informal form (present or past) are used before のに.

Despite it being expensive, it is not good.

Even though it was cold, I went out.

Note

のに cannot be followed by a command, request, or suggestion. For example, you cannot say 'It is raining so please use an umbrella' using のに. Use ので or から for those situations instead.

な-Adjective or Noun + な / だった + のに

When using な-Adjectives or Nouns with のに in the present tense, the particle な must be added.

な-Adjective

Add な to the stem of a な-Adjective in the present tense. Use だった for the past tense.

Even though he is healthy, he does not work.

Although it was quiet, I could not sleep.

Noun

Add な after a Noun in the present tense. Use だった for the past tense.

Despite being a student, he has no money.

Even though it was Sunday, I worked.

Note

In the past tense, だった is used instead of な. Be careful not to use だ before のに in the present tense.
