You can turn an い-adjective into an adverb by changing the final い to く. This allows the adjective to modify a verb. Key points: • い → く makes an adverb • Adverbs describe how an action is done • Works for all い-adjectives • Example: 早い → 早く (quickly) For example, “早く起きます” means “I wake up early.” “ゆっくり” is already an adverb, but many adverbs are made from い-adjectives. Another example: “おいしい” becomes “おいしく,” and you can say “おいしく食べます” (I eat deliciously). This pattern is very useful for adding detail to actions. Once you know an い-adjective, you can easily make an adverb and use it with verbs. Practice: 大きい → 大きく, 速い → 速く, 安い → 安く.
