母 is the plain word for my mother / one’s mother when speaking about her to someone else.

A very common pattern in Japanese is:

• use a plain / humble-family term for your own family when talking to outsiders
• use a more respectful form like お母さん when addressing your mother directly, or sometimes when referring to someone else’s mother

So in a sentence like this, 母は... is very natural.

A rough comparison:

• 母 = my mother / my mom (neutral, used in explanation or narration)
• お母さん = Mom / mother (more respectful, often used when talking to her or by children)

In textbook-style example sentences, 母 is especially common.

は marks 母 as the topic of the sentence.

So 母は means something like:

• As for my mother, ...
• My mother, ...

It does not simply mean “mother is” in the same way English uses is. Instead, it sets up what the sentence is about, and the rest of the sentence tells you what is true about that topic.

Here:

• 母は = As for my mother,
• 朝のうちに玄関を掃いて、部屋をきれいにします。 = she sweeps the entryway in the morning and makes the room clean.

朝のうちに means something like:

• in the morning
• while it is still morning
• before morning is over

It has a nuance of doing something within that time period, before it passes.

So it is a little more specific than just 朝に, which simply means in the morning.

Compare:

• 朝に = in the morning
• 朝のうちに = while it’s still morning / before noon / during the morning time

This expression often suggests getting something done early.

In this sentence, うち means something like during, within, or while still in a certain time or condition.

So:

• 朝のうち = during the morning / while it is still morning

This is a useful pattern:

• 〜のうちに = while still ~ / within ~ / before ~ ends

Examples of the same idea:

• 熱いうちに食べる = eat it while it’s still hot
• 若いうちに勉強する = study while you’re still young
• 午前中のうちに終わらせる = finish it within the morning

So in your sentence, 朝のうちに emphasizes the action being completed before morning is over.

The に marks the time frame as the point or period by/in which the action happens.

With 〜のうちに, the whole phrase works as a set expression:

• 朝のうちに = within the morning / while it is still morning

So the に is part of that common grammar pattern.

You can think of it as marking the time during which or before the end of which the action is done.

玄関 is the entryway, front entrance, or genkan of a house.

In Japanese homes, the 玄関 is the area just inside the door where people enter and remove their shoes. It is a very culturally important space, so it is often treated as a specific area of the home, not just “the door.”

So 玄関を掃いて means sweeping that entrance area.

掃いて is the て-form of 掃く.

• dictionary form: 掃く = to sweep
• polite non-past: 掃きます
• て-form: 掃いて

The て-form is being used to connect two actions:

• 玄関を掃いて、
• 部屋をきれいにします。

So the meaning is basically:

• She sweeps the entryway and makes the room clean.

This is a very common way to link actions in Japanese.

Also note the verb change:

• 掃く ends in く
• verbs ending in く usually change to いて in the て-form
• so 掃く → 掃いて

Usually, yes.

In a sentence like this, the て-form often suggests actions in sequence:

1. sweep the entryway
2. make the room clean / tidy the room

So the natural reading is that your mother does these actions as part of her morning routine, with the first leading into the second.

That said, the て-form is flexible. Depending on context, it can show:

• sequence
• accompanying actions
• cause/reason
• method

Here, sequence is the most natural interpretation.

The comma is mainly there to make the sentence easier to read.

Japanese commas often show:

• a pause
• separation between parts
• easier reading of connected actions

In this sentence, it separates the two linked actions:

• 玄関を掃いて、
• 部屋をきれいにします。

The sentence would still be understandable without the comma in many cases, but the comma is very natural in writing.

This is the pattern:

• Noun を
• adjective/noun + に
• する

It means to make something ~.

So here:

• 部屋 = room
• を = marks the thing affected
• きれいに = cleanly / clean, as the resulting state
• します = do / make

Together:

• 部屋をきれいにします = make the room clean

In natural English, that often becomes:

• clean the room
• tidy the room

So this is not just be clean; it is an action that changes the room into a clean state.

Because this sentence uses the pattern 〜にする, meaning to make ~.

きれい is a na-adjective. When a na-adjective is used before する to show the result of a change, it takes に:

• 静か → 静かにする = make it quiet
• きれい → きれいにする = make it clean

So:

• 部屋はきれいです = The room is clean.
• 部屋をきれいにします = (Someone) makes the room clean.

That is a very important difference.

Both are possible in Japanese, but they mean slightly different things.

部屋をきれいにします

• focuses on the person doing the action
• means someone makes the room clean
• uses する, a transitive expression

部屋がきれいになります

• focuses on the room’s change of state
• means the room becomes clean
• uses なる, an intransitive expression

In your sentence, the mother is actively cleaning, so 部屋をきれいにします is the better choice.

Because both nouns are the direct objects of their verbs.

• 玄関を掃いて = sweep the entryway
• 部屋をきれいにします = make the room clean

In the second part, 部屋 is still the thing being affected by the action, so it takes を.

The structure is:

• X を Y にする = make X into Y

So:

• 部屋をきれいにする = make the room clean

Yes, but in this pattern it means more like make rather than a plain do.

On its own:

• する = to do

But in combinations like:

• きれいにする
• 静かにする
• 元気にする

it means:

• make clean
• make quiet
• make healthy/energetic

So します is the polite form of する, but the whole expression きれいにします is best understood as makes it clean / cleans it up.

By itself, it can very naturally describe a habit or routine.

That is because:

• the sentence is in the non-past polite form: します
• there is no specific past-time marker
• the context sounds like a general description of what the mother does

So a natural interpretation is:

• My mother sweeps the entryway in the morning and tidies the room.

If you wanted to make it clearly past tense for one occasion, you would use forms like:

• 掃いて、部屋をきれいにしました。

Then it would clearly mean she did those actions on a particular occasion.
