Korean Shades of Guessing: -는 듯하다, -으려나 보다
Korean softens a guess with -는 듯하다 (모두 떠난 듯해요 — everyone seems to have left) and wonders aloud about what's coming with -으려나 보다 (비가 오려나 봐요 — looks like it might rain), letting you place each conjecture on a ladder of confidence from hunch to evidence.

Korean lets you fine-tune a guess: -는 듯하다 gives a soft, slightly literary “it seems” (모두 떠난 듯해요 — everyone seems to have left; 비가 온 듯해요 — it looks like it rained), and -으려나 보다 wonders aloud about something on the verge of happening (비가 오려나 봐요 — looks like it might be about to rain; 손님이 오려나 봐요 — seems guests are about to arrive). Grade 5 is the level of nuance, and few areas have more shades than guessing.
You already guess with -것 같다, -나 보다, and -는 모양이다. The skill now isn’t learning another way to guess — it’s hearing where each one sits on a ladder of confidence: which is a vague hunch, which leans on evidence, which sounds soft and refined. After you react with -다니 and -는걸, this is how you hedge like a native. Start with the words of speculation.
Ten words for guessing
These let you hedge, infer, and read the signs.
It seems… (softly) — -는 듯하다
To say something seems or appears so, in a soft, slightly literary tone, use -는 듯하다. It’s the refined cousin of -는 것 같다 — same meaning, gentler register.
비가 오는 듯해요. = it seems to be raining. 불이 꺼진 걸 보니 모두 떠난 듯해요. = by the dark windows, everyone seems to have left. 생각보다 일이 많은 듯하다. = there seems to be more work than expected. 곧 도착할 듯합니다. = it appears (they) will arrive soon.
It conjugates just like -는 것 같다: present action -는 듯하다 (가는 듯하다), past -(으)ㄴ 듯하다 (간 듯하다, 떠난 듯해요), adjective -(으)ㄴ 듯하다 (많은 듯하다), future -(으)ㄹ 듯하다 (올 듯하다). Default to -는 것 같다 in casual talk; pull out -는 듯하다 when you want a softer, more polished feel.
Looks like it might… — -으려나 보다
To wonder aloud about something about to happen — a forward-looking, half-to-yourself guess — use -(으)려나 보다. The 려나 carries an “I wonder if…” tone.
하늘을 보니 비가 오려나 봐요. = by the sky, looks like it might rain. 초인종이 울리네, 손님이 오려나 봐요. = the doorbell — seems guests are about to arrive. 애가 눈을 비비네, 자려나 봐요. = she’s rubbing her eyes — looks like she’s about to sleep. 표정을 보니 화가 나려나 보다. = by his face, looks like he’s about to get angry.
It builds on the -나 보다 you already know (a guess from evidence) but adds the “about to / on the verge” feel and a wondering, tentative tone — softer than a flat -(으)ㄹ 거예요 prediction. Reach for it when an event seems imminent but you’re not sure.
The confidence ladder
Here’s how the new forms slot in among the ones you know — ranked from vaguest hunch to firmest read of the evidence:
-(으)ㄹ 듯하다 / -으려나 보다 = softest, tentative hunch (올 듯해요, 오려나 봐요) -는 것 같다 = everyday neutral ‘seems’ — your default (오는 것 같아요) -나 보다 = a guess read from evidence (불이 켜진 걸 보니 오나 봐요) -는 모양이다 = ‘by the looks of it’ — leans hardest on visible signs (오는 모양이에요)
The trick: -는 듯하다 sits right beside -는 것 같다 in meaning but sounds softer and more literary. -는 모양이다 implies the most concrete evidence (“by all the signs”). -으려나 보다 is the tentative, forward-looking hunch. None is as sure as a flat -(으)ㄹ 거예요 — they all hedge to some degree. Pick by how much you can actually see and how soft you want to come across.
Guessing at the weather and a friend’s mood
Two friends reading the signs — the new forms beside the old, live:
Watch the shades: 오려나 봐/지치려나 봐 wonder about what’s coming, 쏟아질 듯해/그칠 듯하니까 soften the guess, and 힘든 모양이네 reads the hardest evidence off a face. Same situation, four different confidence levels.
FAQ
How is -는 듯하다 different from -는 것 같다? They overlap almost entirely in meaning — both say ‘it seems / appears’ — but they differ in register. -는 것 같다 is the everyday, neutral default you’ll use constantly in speech: 비가 오는 것 같아요 = it seems to be raining. -는 듯하다 is softer and a touch more literary or refined, common in writing, news, and careful speech: 비가 오는 듯하다 / 모두 떠난 듯해요. Conjugation mirrors -는 것 같다: present action -는 듯하다 (가는 듯하다), past -(으)ㄴ 듯하다 (간 듯하다), adjective -(으)ㄴ 듯하다 (예쁜 듯하다), future -(으)ㄹ 듯하다 (올 듯하다). Use -는 것 같다 by default; reach for -는 듯하다 when you want a gentler, more polished tone.
What nuance does -으려나 보다 add over -나 보다? -나 보다 (taught earlier) is a guess from evidence about a current state: 자나 봐요 = (judging by the quiet) they must be asleep. -(으)려나 보다 adds the ‘about to / will’ flavor of -(으)려고 plus a wondering tone — you’re guessing about something on the verge of happening, half asking yourself. 비가 오려나 봐요 = looks like it might be about to rain (I wonder). 손님이 오려나 봐요 = seems like guests are about to arrive. The 려나 makes it feel tentative and forward-looking, softer than a flat -(으)ㄹ 거예요 prediction. Use it for imminent events you’re not sure about.
How do I rank all these guessing forms by confidence? Think of a ladder. Lowest, vaguest hunch: -(으)ㄹ 듯하다 / -으려나 보다 — soft, tentative, often half to yourself (올 듯해요, 오려나 봐요). Middle, everyday neutral: -는 것 같다 — your default ‘seems’ (오는 것 같아요). Reading visible evidence: -나 보다 and -는 모양이다 — ‘by the looks of it’ (오나 봐요, 오는 모양이에요), where 모양이다 leans hardest on observable signs. The new -는 듯하다 sits beside -는 것 같다 in meaning but softer/more literary in tone. None of these is as certain as a plain -(으)ㄹ 거예요 prediction — they all hedge. Pick by how much evidence you have and how soft you want to sound.
