With 前に, Japanese normally uses:

• dictionary form + 前に for verbs
• noun + の + 前に for nouns

So:

• 会社に行く前に = before going to the company / before going to work

The dictionary form is standard here because it means before that action happens.

Compare:

• 行く前に = before going
• 行った後で = after going

So 前に looks forward to an action that has not happened yet, while 後で / 後に often follows a completed action.

Also, 行きます前に is not correct, because polite -ます form does not normally connect directly to grammar like 前に.

They are doing two different jobs:

1. 会社に行く

   • に marks the destination of 行く
   • 会社に行く = go to the company

2. 行く前に

   • this に belongs to the grammar pattern 前に
   • 前に means before

So even though you see に twice, they are part of different pieces:

• 会社に行く = go to work
• 行く前に = before going

Together:

• 会社に行く前に = before going to work

前に means before.

In this sentence, it sets the time frame for the following actions:

• 会社に行く前に、支度をして、駅前のコンビニに寄ります。
• Before going to work, I get ready and stop by the convenience store near the station.

So everything after 前に is something done before going to work.

A useful pattern to remember:

• Verb dictionary form + 前に = before doing X
• Noun + の + 前に = before X

Examples:

• 寝る前に = before sleeping
• 食事の前に = before the meal

Both can be heard, but 支度をして is the fuller, more textbook-like form.

支度 is a noun meaning preparation / getting ready, and it often combines with する:

• 支度をする = to get ready / to prepare

Its て-form is:

• 支度をして

In casual speech, people may sometimes shorten noun + をする expressions, but 支度をして is very natural and clear.

支度（したく） means preparation or getting ready.

In everyday use, 支度をする often means:

• getting ready to go out
• getting dressed
• preparing what you need before leaving

So in this sentence, 支度をして probably means something like:

• get ready
• get dressed
• prepare to leave for work

It is a very common word for daily routines.

して is the て-form of する.

Here it connects actions in sequence:

• 支度をして、駅前のコンビニに寄ります。
• I get ready, and then stop by the convenience store near the station.

The て-form often means:

• and
• and then
• after doing

So the sentence has one final main verb in polite form:

• 寄ります

Everything before that is linked to it:

• 支度をして = get ready, and...
• 駅前のコンビニに寄ります = stop by the convenience store

This is very common in Japanese: earlier actions use て-form, and the final action carries the tense/politeness.

Yes. The natural order is:

1. 会社に行く前に = before going to work
2. 支度をして = get ready
3. 駅前のコンビニに寄ります = stop by the convenience store near the station
4. then go to work

The て-form strongly suggests a sequence:

• do A, then do B

And the 前に phrase tells you that both of those actions happen before going to work.

駅前（えきまえ） literally means in front of the station.

It is a very common compound noun:

• 駅 = station
• 前 = front / before
• 駅前 = the area in front of the station, or near the station entrance

So:

• 駅前のコンビニ = the convenience store in front of the station / near the station

In natural English, people often translate it as:

• the convenience store by the station
• the convenience store near the station

の links nouns together.

Here:

• 駅前 = in front of the station / station-front area
• コンビニ = convenience store

So:

• 駅前のコンビニ = the convenience store at the station-front area

You can think of の here as working like:

• the station-front convenience store
• the convenience store near the station

This is a basic Japanese noun-modifying pattern:

• A の B = B of A / B related to A

The verb 寄る often uses に to mark the place where someone stops by.

So:

• コンビニに寄る = stop by the convenience store

This is just the natural particle pattern for this verb.

Examples:

• スーパーに寄る = stop by the supermarket
• 友だちの家に寄る = stop by a friend’s house

Even though English might use by or at, Japanese commonly uses に with 寄る.

Not quite.

• 行きます = go
• 寄ります = stop by / drop in / make a quick stop

So 駅前のコンビニに寄ります does not just mean go to the convenience store. It suggests:

• the speaker is going somewhere else eventually
• the convenience store is a brief stop on the way

That fits this sentence well, because the main destination is work.

This is a very common Japanese pattern.

In a sentence like this:

• the main verb is often in the polite form
• verbs inside modifying clauses or grammar patterns usually stay in the plain form

So:

• 会社に行く前に
  plain form inside the 前に structure

• 寄ります
  final main verb in polite style

This is normal and correct Japanese. You do not need to make every verb polite just because the sentence ends politely.

In many contexts, yes.

Literally:

• 会社に行く = go to the company

But in natural usage, it often means:

• go to work
• go to the office

Because Japanese frequently refers to the workplace itself:

• 会社 = company / office
• 会社に行く = go in to work

So depending on context, English may translate it more naturally as go to work.

Japanese often leaves out the subject when it is obvious from context.

So this sentence does not explicitly say:

• 私は
• 僕は
• 彼は

But a listener usually understands the subject from the situation.

In an isolated example sentence, the natural assumption is often:

• I get ready and stop by the convenience store before going to work

This omission is extremely common in Japanese and is one of the biggest differences from English.

The most natural reading is that it applies to both actions:

• before going to work,
  • get ready
  • stop by the convenience store

Because 会社に行く前に appears at the beginning and sets the time frame for the whole rest of the sentence.

So the sentence is best understood as:

• Before going to work, I get ready and stop by the convenience store near the station.

If someone wanted to make the scope narrower or different, they would usually phrase it more explicitly.

Yes, 前 is originally a noun meaning front or before.

That is why you see:

• 名詞 + の + 前に
  example: 食事の前に = before the meal

But after a verb, you do not use の:

• 食べる前に = before eating
• 行く前に = before going

So:

• with nouns: の is needed
• with verbs: use the plain form directly before 前に

That is why:

• 会社に行く前に is correct
• 会社に行くの前に is not correct here

It is very natural and typical Japanese.

It uses several common patterns that learners should know well:

• Verb dictionary form + 前に
• noun + をして
• て-form to connect actions
• place + に + 寄る
• omitted subject
• noun modification with の

So it is a good example of everyday spoken or written Japanese about a daily routine.
