Learn Hardcore Chinese: tā xiànzài zhù zài gōngsī pángbiān, zuò dìtiě hěn fāngbiàn. - She now lives near the company; taking the subway is very convenient.

Here 在 is a preposition/coverb meaning “at/in,” marking the location of the verb 住 “to live.” It is not the progressive marker. The progressive 在 appears before an action verb (like 在看书 “be reading”), but with 住 we normally express location with 住在 + place, not 在住 or 住着 + place in everyday speech.

Do I have to include 在 after 住? Can I say 住公司旁边?

Both 住在公司旁边 and 住公司旁边 are acceptable. 住在 is the most common, especially with specific or longer locations; 住 + place is also fine and a bit more succinct. Meaning is the same: “live at/by ….”

Why is it 公司旁边 and not 公司的旁边? When do I use 的?

With “location nouns” like 旁边/里面/外面/附近, native speech often drops 的: 公司旁边 is very natural. 公司的旁边 is not wrong but sounds a bit heavier; you’d keep 的 if the possessor is long or needs clarity (e.g., 在我朋友新开的那家公司的旁边).

What’s the difference between 旁边 and 附近?

旁边: right next to, adjacent to (very close, often side-by-side).
附近: nearby/in the vicinity (close, but not necessarily adjacent). So 公司旁边 ≈ right next to the company; 公司附近 ≈ somewhere near the company.

Is the word order Subject + 现在 + 住在 + place the only option? Where can 现在 go?

Time expressions are flexible:

她现在住在公司旁边 (subject + time + verb …) — very common.
现在她住在公司旁边 — puts extra focus on “now.” Both are correct. General template: Subject + Time + (在 + Place) + Verb … or Subject + Time + Verb + 在 + Place … (with 住, 住在 + place is the most natural).

Can I say 在公司旁边住 instead of 住在公司旁边?

Yes: 她现在在公司旁边住 is grammatical and puts the place up front as the scene/topic. With 住, post-verbal 住在 + place is more common, but preposing the place (在公司旁边住) is fine for emphasis or flow.

Why is there no 了 after 住? When would 了 be used?

Without 了, it neutrally states her current situation. Add 了 to highlight a change/new situation:

她现在住在公司旁边了 = Now she lives next to the company (she didn’t before).

Does 很 in 很方便 really mean “very,” or is it just a linker?

In adjective predicates, 很 often works as a “default linker” to make the sentence sound natural and non-comparative. Here 很方便 can mean “(very) convenient,” but often reads as simply “convenient” without strong emphasis. Omitting 很 (坐地铁方便) is also possible and can sound slightly more neutral/factual; with some adjectives, dropping 很 can imply comparison.

Who is the subject of 坐地铁很方便? Do I need to repeat 她?

Chinese often omits repeated or obvious subjects. Here the second clause is a general statement: “Taking the subway is convenient (from there).” If you want to specify the person, you can say:

她坐地铁很方便 (It’s convenient for her to take the subway.)
对她来说，坐地铁很方便 (From her perspective, it’s convenient.)

Does 坐 literally mean “to sit”? Why use 坐 with 地铁?

Yes, 坐 literally means “to sit,” but with transport it means “to take/ride.”

Common: 坐地铁/坐火车/坐飞机/坐公交/坐船/坐出租车
Drive yourself: 开车
Ride (straddle): 骑自行车/骑摩托车/骑马 Formal alternative: 乘/乘坐, and in Taiwan you’ll often hear 搭 (e.g., 搭捷运/搭公车).

Is 地铁 the same as “subway station”? Why not 坐地铁站?

地铁 = the subway system. 地铁站 = subway station.
You say 坐地铁 (“take the subway”), but you 去地铁站 (“go to the subway station”). “坐地铁站” is incorrect.

How does this punctuation work? Why a comma between the two parts?

Chinese uses commas more freely to join related clauses. The comma here implies a cause–result relation. You can make it explicit:

她现在住在公司旁边，所以坐地铁很方便。 You could also write two sentences; both are fine.

What’s the difference between 地铁很方便 and 坐地铁很方便?

地铁很方便: The subway (as a system) is convenient (to use).
坐地铁很方便: Taking the subway (from that place/for that person) is convenient. The second ties convenience to the action, not just the system.

Could I drop 现在? Would it change the meaning?

Yes: 她住在公司旁边，坐地铁很方便。
Chinese often relies on context for time. Adding 现在 highlights contrast with another time (e.g., she used to live elsewhere).

Any regional wording differences for “subway” and “take the subway”?

Mainland: 地铁, say 坐地铁/乘地铁.
Taiwan: 捷运 (jiéyùn), commonly 搭捷运.
Hong Kong: 地铁/港铁 (MTR), often 搭地铁/搭港铁. All are mutually intelligible in context.

Is 方便 an adjective here? Could it be a verb?

Here 方便 is an adjective meaning “convenient.” It can also be:

A polite verb/adjective: 方便吗？ (“Is it convenient [for you]?”)
A euphemism for “use the restroom” in set phrases: 我去方便一下。 Context disambiguates easily.
