手続き means procedure, formal process, or paperwork. It is often used for things like administrative steps, applications, registrations, official business, and similar tasks.

In this sentence, 手続きが終わった means the procedures finished or the paperwork was completed.

が marks 手続き as the thing that ended.

• 手続きが終わった = the procedures ended / were finished
• The verb 終わる is intransitive, so the thing that ends is marked with が

If you used を, that would not work with 終わる.
If you used は, the sentence would sound more like a topic statement: as for the procedures, they finished. That is possible in some contexts, but が is the most natural basic choice here.

They come from different verb types and have different grammar:

• 終わる = to end (intransitive)
• 終える = to finish something (transitive)

So:

• 手続きが終わった = the procedures ended / were completed
• 手続きを終えた = someone finished the procedures

The sentence uses 終わった, which focuses on the procedures being over, rather than strongly emphasizing the person who completed them.

Both ので and から can mean because / so, but ので usually sounds a bit softer, more natural, and more explanatory.

• 終わったので、買って帰った = Since it was finished, I bought lunch and went home
• 終わったから、買って帰った would also be correct, but it can sound a little more direct or casual

So ので fits well when calmly giving the reason for what happened next.

It can be translated in several ways depending on the context:

• because
• since
• so

In this sentence, it links the first event to the next action:

• やっと手続きが終わったので = since the procedures finally ended / because the procedures were finally done

English translations may vary, but the grammar role is the same: it gives the reason or background for the following action.

駅前 literally means in front of the station, but in natural English it often means the area in front of the station or near the station.

So 駅前で means the action of buying lunch happened at the station front area / near the station.

It does not necessarily mean standing directly in front of the station building. It often refers more generally to the busy area around the station.

The particle で marks the place where an action happens.

Here, the action is 買って (buying), so:

• 駅前で昼ご飯を買って = bought lunch at/near the station

If the sentence were only about existence or location, a different particle like に might be used in other contexts, but for an action taking place somewhere, で is the normal choice.

昼ご飯 means lunch.

You may also see:

• 昼ごはん
• 昼ご飯
• ランチ

These are all common, but they have slightly different feel:

• 昼ごはん / 昼ご飯 = ordinary Japanese word for lunch
• ランチ = loanword from English, often used for a lunch meal, especially in restaurants or casual conversation

The choice here sounds very normal and everyday.

を marks the direct object of 買う (to buy).

So:

• 昼ご飯を買って = bought lunch

The speaker is buying lunch, so 昼ご飯 is the thing directly affected by the action.

Yes, it is a sequence of actions connected by the て-form:

• 買って = bought
• 帰った = went home / returned

So 昼ご飯を買って帰った means:

• bought lunch and went home
• or more naturally, bought lunch on the way home

The て-form often links actions in order. Here, the buying happened first, then the going home happened after that.

帰る means to return or to go back, often to a place considered one’s base, such as:

• home
• one’s hometown
• one’s office
• one’s usual place

In many everyday situations, especially without a stated destination, 帰った is often understood as went home. But depending on context, it could also mean simply returned.

Japanese often omits information that is obvious from context.

If the listener already knows where the speaker returned to, there is no need to say it. So 帰った by itself can be completely natural.

If the speaker wanted to be more specific, they could say:

• 家に帰った = went home
• 会社に帰った = went back to the office

But omission is very common in Japanese.

The subject is omitted because Japanese often leaves out things that are understood from context.

From the sentence, we can infer that the same person:

1. finally finished the procedures,
2. bought lunch near the station,
3. and went home

In English, we usually need a subject like I, but in Japanese it is often not said when it is obvious.

The main actions are in the past tense:

• 終わった = ended / was finished
• 帰った = went home / returned

So the whole sentence describes a past sequence of events.

Even though 買って is not itself marked with -た, it is linked to the final past verb 帰った, so the whole sequence is understood as past.

Yes. It is a complete clause meaning:

• since the procedures finally ended
• because the procedures were finally finished

Its structure is:

• やっと = finally
• 手続きが = the procedures
• 終わった = ended / were completed
• ので = because / since / so

This clause gives the reason for the main action in the second part of the sentence.

No. The order is clear from the grammar.

First:

• やっと手続きが終わった = the procedures finally ended

Then, because of that:

• 駅前で昼ご飯を買って帰った = bought lunch near the station and went home

The ので shows that the first clause is the reason or background for the second. The て-form then links the later actions in sequence.

That is because 駅前 is a fixed compound noun meaning in front of the station / station-front area.

It is not being built freely as 駅の前 here, although that version also exists.

• 駅前 = station-front area, often treated as a single place name or location word
• 駅の前 = directly in front of the station

In this sentence, 駅前 sounds very natural because it refers to the general area around the station.

It breaks down like this:

• やっと = finally
• 手続きが終わった = the procedures finished
• ので = so / since / because
• 駅前で = at/near the station
• 昼ご飯を買って = bought lunch
• 帰った = went home

So the structure is:

[reason/background] + [place of action] + [action 1] + [action 2]

A very natural English rendering would be:

The procedures finally finished, so I bought lunch near the station and went home.
