Linking and Adverbs: 〜くて and 〜く

An i-adjective can do more than end a sentence.

Linking with くて: drop the final い and add くて to join the adjective to another adjective or to a clause. It means "and", and often also "so" or "because":

• このかばんは軽くて、便利です。(This bag is light and handy.)
• 暑くて、眠れません。(It's so hot that I can't sleep.)

The くて form never shows tense. The end of the sentence does that.

Adverbs with く: drop い and add く to describe a verb: 早い → 早く起きます (get up early), 強い → 強く押します (press hard). Use the same form before します and なります: 部屋を暖かくします (warm up the room).

The irregular いい becomes よくて and よく.
