With time words like 朝 (morning), Japanese often leaves out に.

So both of these can work:

• 朝、ごみを持って外に出て、捨てます。
• 朝に、ごみを持って外に出て、捨てます。

But 朝 without a particle is more natural in many everyday sentences.

A good rough rule:

• Common time words such as 今日, 明日, 昨日, 朝, 毎日 often do not need に
• More specific times like 7時, 月曜日, 3月5日 often do use に

を marks the direct object of the verb.

Here, ごみを means the garbage is the thing being handled in the action:

• you carry the garbage
• you throw away the garbage

Even though there are two verbs later, ごみ is understood as the object connected to the whole action sequence.

持って is the て-form of 持つ.

The て-form is used to connect actions. Here it links one action to the next:

• ごみを持って = carrying / taking the garbage
• 外に出て = go outside
• 捨てます = throw it away

So the sentence shows a sequence:

1. take the garbage
2. go outside
3. throw it away

If you used 持ちます here, it would sound like a separate sentence unless you added extra structure.

In this sentence, the て-form mainly means and then or doing X, then Y.

So:

• 持って connects to 出て
• 出て connects to 捨てます

It creates a chain of actions in order.

Important point: the て-form does not itself show tense. The final verb, 捨てます, tells you the overall tense and politeness of the sentence.

Because 出る usually takes a destination or resulting location with に.

• 外に出る = go outside
• literally, exit to the outside

Here, 外 is the place you end up in, so に is natural.

This is a very common pattern:

• 部屋に入る = enter the room
• 家に帰る = return home
• 外に出る = go outside

Yes, 出る means to go out, to come out, or to leave.

In 外に出る, it means to go outside.

So the phrase is not just about physically exiting something in an abstract way. It specifically describes moving from inside to outside.

That is why 外に出て feels natural here: after taking the garbage, you go outside.

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

So even though English usually needs something like I or we, Japanese often does not say it if the listener can figure it out.

In this sentence, the subject is omitted because it is understood from context:

• I take out the garbage...
• we take out the garbage...
• someone takes out the garbage...

Japanese is very comfortable with this kind of omission.

Japanese non-past covers both:

• present/future actions
• habitual actions

So 捨てます can mean:

• I throw it away
• I will throw it away
• I throw it away regularly / as part of a routine

In a sentence like this, it often sounds like a habitual or typical action, especially with 朝 at the beginning.

It can be understood in several similar ways depending on context.

持つ basically means to hold or to carry, but in connected action sentences like this, 持って often feels like:

• take
• carry
• bring

In natural English, this sentence is often rendered as something like:

• In the morning, I take the garbage outside and throw it away.

So even though the core meaning is carry/hold, the best English translation may use take.

Yes. 外 means outside and behaves like a noun.

That is why it can take a particle:

• 外に = to the outside / outside

Japanese often uses location words like nouns:

• 中 = inside
• 外 = outside
• 上 = above/on top
• 下 = below/under

So 外に出る is literally something like go to outside, which becomes go outside in natural English.

The commas help show the rhythm and structure of the sentence.

They separate:

• the time expression: 朝、
• the connected actions: 出て、

Japanese commas are often more flexible than English commas. They do not always follow exactly the same strict rules as in English. Here they mainly make the sentence easier to read.

Yes. Japanese often has multiple natural ways to say the same thing. For example:

• 朝、ごみを外に持って行って、捨てます。
• 朝、ごみを外に出して、捨てます。

These are similar, but the nuance changes a little:

• 持って行って emphasizes taking/carrying it out
• 出して can sound like putting it out / taking it out
• 持って外に出て emphasizes carrying it and then going outside

So the original sentence is perfectly understandable, but it is not the only possible phrasing.

Yes. Japanese usually presents actions in the order they happen.

So this sentence naturally means:

1. in the morning
2. take/carry the garbage
3. go outside
4. throw it away

Because the verbs are connected with the て-form, the listener understands them as a sequence of events.
