Learn Hardcore Korean: gonghangeseo suksokkaji ganeun yogeumgwa hwanseung hoessuga aebe pyosidwaeyo. - The fare and number of transfers from the airport to the accommodation are shown in the app.

에서 after a place marks the starting point of a movement or the place where an action happens. Here it means “from the airport.”
- Example: 공항에서 숙소까지 가요. = I go from the airport to the lodging.
부터 also means “from,” often used for ranges (time/space). With places it’s possible, but in a movement clause like this, 공항에서 … 가는 is more idiomatic than 공항부터 … 가는.
에 marks a static location or destination. You can say 공항에서 숙소에 가요 (“go from the airport to the lodging”), but 에서 … 까지 is the standard symmetric pair for “from … to …” in route descriptions.

Why is it 숙소까지 instead of 숙소에? Are both OK?

까지 means “up to/as far as,” forming the set pattern A에서 B까지 for routes. It emphasizes the endpoint boundary.
숙소에 marks the destination without the boundary nuance. 공항에서 숙소에 가는 요금 is understandable, but 공항에서 숙소까지 가는 요금 is more natural when you’re describing the whole route from A to B.

What exactly is 가는 doing?

가는 is the adnominal (attributive) form of 가다 (“to go”), making a relative clause that modifies the following noun(s).
So 공항에서 숙소까지 가는 = “(the) going from the airport to the lodging,” and it modifies 요금 and 환승 횟수: “the fare and number of transfers for going from the airport to the lodging.”

Does 가는 modify both 요금 and 환승 횟수, or just 요금?

It modifies both. In Korean, one relative clause can modify a coordinated noun phrase:
- [공항에서 숙소까지 가는] [요금과 환승 횟수].
If you wanted to be hyper-explicit, you could repeat it: 공항에서 숙소까지 가는 요금과 공항에서 숙소까지 가는 환승 횟수, but that’s redundant.

Could I drop 가는 and say 공항에서 숙소까지 요금과 환승 횟수?

It’s possible but feels choppier. For 요금, sometimes people omit the verb and say 공항에서 숙소까지 요금 (“fare from A to B”). For 환승 횟수, omitting 가는 sounds less natural. Keeping 가는 ties the route to both nouns smoothly.
Another very natural option is: 공항에서 숙소까지 갈 때 드는 요금과 환승 횟수 (“the fare and number of transfers incurred when going …”).

Why use the passive 표시돼요 instead of an active verb? What would the active version be?

Korean often describes on-screen information with passives to highlight the result/state: “are displayed,” 표시돼요 (from 표시되다).
Active alternatives:
- 앱에서 (요금과 환승 횟수를) 표시해요. = “The app displays …”
- 앱에서 보여줘요. = “The app shows …”
- The passive 앱에 … 표시돼요 focuses on the info itself being present on the app.

Why 앱에 and not 앱에서?

With passives/stative expressions (e.g., 보여요, 나와요, 표시돼요), 에 marks the surface/location where something appears: “on the app.”
앱에서 with a passive can sound off; 앱에서 suits active verbs when the app is the agent/doer: 앱에서 표시해요/보여줘요.

Is 되요 a spelling mistake? Why is it 돼요?

Correct: 돼요. It comes from 되어요 (doe- + -어요) contracting to 돼요. Writing 되요 is a common error.
Both 되어요 and 돼요 are acceptable orthographically, but 돼요 is the usual form.

What’s the politeness level of -돼요, and what are other options?

-어요/-아요 (here 표시돼요) is polite informal, neutral.
More formal: 표시됩니다 (written/announcements/UI text).
Casual: 표시돼 (drop 요).
Very formal/honorific to the listener: 표시돼요 is already fine; if you needed subject honorifics (not typical here), you’d rephrase rather than honorify the app.

What do 환승 and 횟수 mean, exactly? How do they relate to 갈아타다 and 번?

환승: “transfer” (in public transit—bus/subway). Verb is 환승하다 or more colloquially 갈아타다 (“to change [vehicles/lines]”).
For flights, 경유 is typically used instead of 환승.
횟수: “number of times/occurrences.” It’s a noun meaning “count of times.”
번 is a counter you put after numbers (한 번, 두 번). So:
- 환승 횟수는 두 번이에요. = The number of transfers is two.
- 환승을 두 번 해요. = (I) transfer twice.

Can I say 환승 수 or 환승 개수 instead of 환승 횟수?

Standard/natural: 환승 횟수.
환승 수 is understood but not the usual collocation.
환승 개수 is off (개수 counts items, not events).

Pronunciation tips for tricky spots like 횟수, 숙소, and 앱에?

횟수 is pronounced roughly [훼쑤]; the ㅅ batchim tensifies the following ㅅ.
숙소 → [숙쏘] (ss sound).
앱에 → [에베] (the ㅂ links to the following vowel).
까지 → [까지] (tense kk).
표시돼요 → [표시돼요] (not [되요]; think “dwae-yo”).
Slow reading: 공-항-에-서 / 숙-소-까-지 / 가-는 / 요-금-과 / 환-승 / 횟-수-가 / 앱-에 / 표-시-돼-요.

Why is the subject marker 가 used (not 이), and where does it attach when there are two nouns?

The marker choice depends on the final sound of the immediately preceding word. 횟수 ends in a vowel sound, so use 가. If it ended in a consonant sound, you’d use 이.
The marker attaches to the entire coordinated phrase: 요금과 환승 횟수 + 가.

Can I reorder parts of the sentence?

Yes. Common variants:
- 앱에 공항에서 숙소까지 가는 요금과 환승 횟수가 표시돼요.
- 공항에서 숙소까지 가는 요금과 환승 횟수는 앱에 표시돼요. (topic focus on the two items)
Korean word order is flexible as long as modifiers stay with their nouns and the verb comes at the end.

What’s the difference among 표시돼요, 보여요, and 나와요 here?

표시돼요: “is displayed” (UI/indicator/label emphasis; technical).
보여요: “is visible/you can see (it)” (perception/user viewpoint).
나와요: “comes out/shows up” (colloquial appearance).
All can work, but 표시돼요 fits UI descriptions best.

Could I use 갈 or 간 instead of 가는? What changes?

가는 (present/habitual) = the route “for going (generally).”
갈 (prospective) would imply a future/intended route: … 갈 요금 (“the fare you will pay to go …”), which can feel oddly predictive in a generic statement.
간 (past) would mean “(the) fare/transfer count for a trip that (someone) went,” not intended here.
For generic route info, stick with 가는.

Is 어플 okay instead of 앱?

Many Koreans say 앱 (from “app”). 어플 (from “application”) is widespread in casual speech but often considered nonstandard or dated. 앱 is preferred in standard/instructional contexts.

How else could I say this naturally?

앱에 공항에서 숙소까지 가는 요금이랑 환승 횟수가 나와요. (more casual with 이랑, 나와요)
앱에서 공항에서 숙소까지 가는 요금과 환승 횟수를 확인할 수 있어요. (active, “you can check …”)
앱이 공항에서 숙소까지 가는 요금과 환승 횟수를 보여줘요. (active, “the app shows …”)

Can you give me a clean breakdown of the whole sentence?

공항에서 = from the airport (origin, 에서)
숙소까지 = up to the lodging (endpoint, 까지)
가는 = going (attributive of 가다, modifying the next nouns)
요금과 환승 횟수 = the fare and the number of transfers (two coordinated nouns)
가 = subject marker for the entire coordinated phrase
앱에 = on the app (location where things appear)
표시돼요 = are displayed (passive, polite)
Natural translation: “On the app, the fare and the number of transfers for going from the airport to the lodging are displayed.”

What’s the standard romanization?

Revised Romanization: Gonghang-eseo sukso-kkaji ganeun yogeum-gwa hwanseung hoessu-ga aeb-e pyosi-dwaeyo.
Note that romanization doesn’t reflect sound changes like 횟수 [훼쑤] or 숙소 [숙쏘]; it’s for spelling, not exact pronunciation.
