처럼: Like

처럼 and 같이: saying something is like something else

Both mean "like" or "as", both attach straight to a noun, and in most sentences you can swap them without anyone blinking. The differences are small but real.

The basic move

• 아이처럼 웃었어요. ai-cheoreom useosseoyo — "She laughed like a child."
• 눈같이 하얘요. nun-gachi hayaeyo — "It's white as snow."

Neither has a 받침 batchim rule, so there's nothing to memorize about consonants and vowels. Attach and go.

Where they differ

처럼 is the neutral one, and it leans slightly literary. If you're describing a quality — someone moved like this, something looked like that — 처럼 is the safer pick and it's what you'll see in writing.

같이 is more conversational, and it carries a whiff of the verb it comes from, 같다 gatda · "to be the same". It sits closer to "just like".

For a learner, the practical advice is: use 처럼 when you mean "like". It's the safe default because it can't be misread as "together", which avoids the ambiguity below.

The 같이 problem

같이 has a second life as an adverb meaning "together", and that's a completely different word doing a completely different job.

• 친구같이 chingu-gachi — "like a friend"
• 친구하고 같이 chingu-hago gachi — "together with a friend"

The first is a comparison. The second is company. What tells them apart is whether 같이 is glued to a noun as a particle or standing on its own as an adverb, usually after a 하고 or 와/과 phrase.

This is the main reason to reach for 처럼 when you mean "like": it can only mean one thing.

처럼 vs 대로

Worth keeping straight, because English translates both as "as".

• 처럼 = resembling. 선생님처럼 말했어요 seonsaengnimcheoreom malhaesseoyo — "I spoke like the teacher," meaning I sounded similar.
• 대로** = following exactly. 선생님이 말한 대로 했어요 seonsaengnimi malhan daero haesseoyo — "I did exactly as the teacher said," meaning I complied.

Similarity versus instruction.

Negatives and comparisons

처럼 shows up constantly in the negative, where it means "not as ... as":

• 저는 형처럼 키가 크지 않아요. jeoneun hyeong-cheoreom ki-ga keuji anayo — "I'm not as tall as my older brother."

Note that this is different from 보다, which ranks two things. 처럼 says they're alike, or in the negative, that they fall short of being alike.

Before a noun: 같은

처럼 and 같이 describe how something is or how it's done. To describe a noun directly, use 같은 gateun, from 같다 gatda:

• 천사 같은 사람 cheonsa gateun saram "a person like an angel"
• 김치 같은 발효 음식 gimchi gateun balhyo eumsik "fermented foods like kimchi"

That second one is the "such as" meaning, and it's very common when giving examples.

"As if": 것처럼

After a verb, add 것처럼 geotcheoreom to say "as if" or "like you …":

• 아무 일도 없었던 것처럼 웃었어요. amu ildo eopseotdeon geotcheoreom useosseoyo "She smiled as if nothing had happened."
• 다 아는 것처럼 말하지 마. da aneun geotcheoreom malhaji ma "Don't talk like you know everything."

처럼 vs 답게

처럼 says you resemble something. 답게 dapge says you really are that thing and you're living up to it.

• 어른처럼 말해요. eoreuncheoreom malhaeyo "He talks like a grown-up." He's a kid.
• 어른답게 행동하세요. eoreundapge haengdonghaseyo "Act like the adult you are."
