If two Koreans say they are 썸 타는 사이, are they dating?
Not quite.
That is exactly why 썸 (sseom) is such a useful Korean word. It describes a stage where two people seem to like each other romantically, but they have not officially become a couple yet.
In English, you might think of a talking stage, something going on, or sometimes a situationship. But none of those is a perfect match.
Sseom meaning: What does 썸 mean?
Quick Answer
썸 usually means a developing romantic connection with some mutual interest, before two people officially start dating.
A simple way to picture it is:
one-sided crush → 썸 → 사귀다
But real relationships are not always that neat. The important part is that there are usually signals going both ways, while the relationship is still not clearly defined as a couple.
So if only one person has feelings and the other person has no idea, Koreans would normally be more likely to describe that as a 짝사랑 — a one-sided crush — not a 썸.
썸 is not just “an ambiguous relationship”
A common explanation says that 썸 is an “undefined relationship.” That is partly true, but it misses something important.
Two friends can have an unclear relationship without being in a 썸.
For Koreans to say two people are 썸 타는 중, there is usually a romantic reading to their behavior. Maybe they text each other often, meet one-on-one, pay unusual attention to each other, flirt, or act in a way that makes friends ask:
Real Example
둘이 썸 타는 거 아니야?
Aren’t you two kind of into each other?
There is no official checklist. One dinner does not automatically mean 썸. One late-night message does not prove it either.
Key Nuance
What matters is the pattern: Do both people seem to be showing interest? And are they still not officially a couple?
That is the key boundary.
Is 썸 the same as a situationship?
Not exactly.
The two ideas overlap because both can describe a romantic connection that has not been clearly labeled as a formal relationship.
But situationship can be broader. In English, it can describe a loosely defined romantic or sexual relationship where the level of commitment is unclear. It can also continue for quite a long time.
썸, on the other hand, more strongly suggests a pre-relationship stage: something is developing, but the two people have not yet crossed into officially 사귀다.
Common Mistake
So “situationship” can sometimes work as a comparison, but it is safer to think:
썸 = mutual romantic interest before the relationship becomes official
rather than:
썸 = situationship
That small difference helps you understand how Koreans actually talk about relationship status.
썸 vs 짝사랑 vs 사귀다
These three expressions are useful because they show three different relationship states.
Comparison
짝사랑
One person likes the other person, but the feelings are not mutual or not known to be mutual.
썸
There seem to be romantic signals from both sides, but the relationship is not official yet.
사귀다
The two people are in an established romantic relationship.
Imagine this conversation:
A: 둘이 사귀어?
Are you two dating?
B: 아니, 아직 안 사귀어. 그냥 썸 타는 중이야.
No, not yet. We’re kind of in that pre-dating stage.
The word 아직 — “not yet” — is important here. It shows that 썸 often points toward a possible next step, even though not every 썸 becomes a relationship.
What does 썸 타다 mean?
You will often hear 썸 타다 or 썸을 타다 rather than just 썸 by itself.
For learners, the easiest approach is to learn 썸 타다 as one expression.
Do not try to translate 타다 here as the same “ride” you see in 버스를 타다 (“ride/take a bus”). In this expression, translating each word separately will not help much.
Here are some natural examples:
요즘 썸 타는 사람 있어?
Is there anyone you’re kind of seeing these days?
나 요즘 그 사람이랑 썸 타는 것 같아.
I think there’s something developing between that person and me.
둘이 썸 타는 거 아니야?
Aren’t those two kind of into each other?
썸인지 친구인지 애매해.
I can’t tell if this is a sseom or just friendship.
나만 좋아하는 거면 썸은 아니지.
If I’m the only one who likes them, that’s not really a sseom.
Notice that the English translations change. That is normal. The Korean word is describing a relationship state, not one fixed English sentence.
So when does 썸 become 사귀다?
This is where Korean learners sometimes get confused.
Two people can meet often, message every day, and even go on what looks like a date — and still say:
아직 안 사귀어.
We’re not dating yet.
Why?
Because behavior and relationship status are not always the same thing.
If both people clearly recognize that they are now a couple, Koreans can describe them as 사귀는 사이. Before that point, if romantic interest is already developing, 썸 may be the word people use.
Key Nuance
This does not mean every Korean couple has a formal “relationship confirmation moment,” or that there is one rule everyone follows. Real relationships vary.
The useful language lesson is simpler:
썸 names the space before the relationship is clearly established.
Where did 썸 come from?
Culture Note
The expression became especially visible in Korean popular culture in the early 2010s.
Korean media in 2014 described 썸 타다 as a popular expression for people exchanging romantic feelings before becoming lovers. That same year, Soyou and Junggigo’s hit song 썸 became one of the biggest songs in Korea and helped make the word even more familiar in mainstream culture.
The word is commonly connected to the English idea of “something” — as in, “There’s something going on between them.”
That makes the feeling behind the word easy to remember: there is clearly something, but the relationship has not been fully defined yet.
The part learners should remember
Practical Takeaway
If someone says:
나 요즘 썸 타고 있어.
Do not translate it automatically as:
“I’m dating someone.”
And do not assume it always means:
“I’m in a situationship.”
A better interpretation is:
“There’s someone I have mutual romantic interest with, but we’re not officially a couple yet.”
That is the real value of learning 썸. It is not just a trendy dating word. It shows how Korean can mark a relationship stage that English often has to explain with a whole phrase.
