く・に-ly: quickly, quietly, well

English turns "quiet" into "quietly" to say how something is done. Japanese changes the い of an い-adjective to く, and adds に to a な-adjective.

い-adjective

早はやい → 早はやく + verb

な-adjective

静しずか + に + verb

いい

いい → よく + verb

All three come before the verb. English usually puts "-ly" words after it.

Before a nounBefore a verb
い-adjective早はやい電でん車しゃ, an early train早はやく起おきる, get up early
な-adjective静しずかな部屋へや, a quiet room静しずかに話はなす, talk quietly
いいいい天てん気き, good weatherよく寝ねる, sleep well

How something is done

きれい ends in い but is a な-adjective, so it takes に. There is no きれく.

Where English has no "-ly"

English often leaves the adjective as it is: "get up early", "cut it short", "write it big". Japanese still changes it, whether it says how you do something or how the thing ends up.

Not said: 毎まい朝あさ、早はやい起おきます。

(I get up early every morning.)

よく: well, and often

よく is the く form of いい. It is "well" in the sense of fully or properly: you sleep well, understand well, listen carefully. It is also the everyday word for "often".

"Well" in the sense of skillfully is 上手じょうずに. よく in its place is usually heard as "often".

Slowly is ゆっくり

Not every "-ly" word comes from an adjective. "Slowly" is ゆっくり, a word of its own. 遅おそく is mostly "late".

When に is something else

After a noun or a verb, に has other jobs.

にN5

After a place, a time or a person it is a particle: in, at, to.

〜に行いくN5

After a verb stem or an activity, it marks what you go somewhere to do.

Close neighbours

With する they mean "make it so". 静しずかにしてください is "please be quiet".

More detail

早はやく and 速はやく

Both are read はやく. 早はやく is early or soon. 速はやく is fast.

すごく

すごく, from すごい (amazing), is an everyday "really". It goes before adjectives too.

近ちかく and 遠とおく

These two are also used as nouns: 駅えきの近ちかく, the area near the station.
