い-Adjective く + Verb

When to use

い-adjectives: drop い, add く (早く起きる). な-adjectives take に.

Explanation

The い-Adjective + く + Verb grammar point transforms an い-adjective into its adverbial form, describing how the verb is performed. In English, this often corresponds to '-ly' adverbs (e.g., 'quickly', 'slowly').

• 彼かれは速く走はしりました。

  He ran quickly.

  Kare wa hayaku hashirimashita.

• この料理りょうりは美味おいしく食たべました。

  I enjoyed eating this dish.

  Kono ryouri wa oishiku tabemashita.

• 彼女かのじょは優やさしく話はなします。

• 母ははは忙いそがしく仕事しごとをしています。
