haha wa daidokoro de tamanegi o kirimasu.

A natural reading is:

母は台所で玉ねぎを切ります。
はは は だいどころ で たまねぎ を きります。

A few pronunciation notes:

• 母 = はは
• The particle は is pronounced wa
• 台所 = だいどころ
• 玉ねぎ = たまねぎ
• The particle を is usually pronounced o
• 切ります = きります

When は is used as the topic particle, it is pronounced wa.

So in this sentence:

• 母 = はは
• は = topic particle, pronounced wa

This is a special pronunciation used only for the particle. The same thing happens with を, which is written を but usually pronounced o.

This is a very common question.

• 母（はは） is typically used when talking about your own mother to other people.
• お母さん（おかあさん） is typically used when talking to your mother, or when referring politely to someone else’s mother.

So 母は台所で玉ねぎを切ります sounds like As for my mother, she cuts onions in the kitchen.

If you said お母さんは..., the nuance would be different.

は marks the topic of the sentence.

Here, 母は means as for mother or speaking of mother.

In simple sentences like this, the topic is often also the person doing the action, so English usually just translates it as the subject:

• 母は → Mother / My mother

But grammatically, は is not exactly the same as an English subject marker. It sets up what the sentence is about.

Strictly speaking, 母 is marked by は, so it is the topic.

In this sentence, though, 母 is also understood to be the person doing the action, so in practice it works like the subject too.

That is very common in Japanese: the topic and the subject are often the same person or thing, even though the grammar is not identical.

で marks the place where an action happens.

So:

• 台所で = in the kitchen / at the kitchen as the location of the action

Since cutting is an action, Japanese uses で for the place where that action takes place.

Compare:

• 学校で勉強します。 = study at school
• 台所で料理します。 = cook in the kitchen

A beginner mistake is to confuse で with に. In sentences like this, で is the correct particle because it marks the location of an action.

を marks the direct object of the verb—the thing being acted on.

Here:

• 玉ねぎを = onion/onions as the thing being cut

So:

• 切ります = cut
• 玉ねぎを切ります = cut onion/onions

You can think of を as showing what receives the action.

Japanese sentences normally place the verb at the end.

So this pattern is very common:

• Topic + place + object + verb

Here:

• 母は = topic
• 台所で = place
• 玉ねぎを = object
• 切ります = verb

That gives:

母は 台所で 玉ねぎを 切ります。

English and Japanese word order are quite different, and getting used to the final verb is an important step in learning Japanese.

切ります is the polite non-past form of the verb.

That means it can express:

• cuts
• will cut
• sometimes a general or habitual action, depending on context

What it usually does not specifically mean is the ongoing progressive is cutting right now. For that, Japanese usually uses:

• 切っています = is cutting

So without context, 切ります is best understood as a polite non-past form, and the exact English translation depends on the situation.

The dictionary form is 切る（きる）.

So:

• 切る = plain/dictionary form
• 切ります = polite form

This verb is a Group 1 / godan verb.

Examples:

• 玉ねぎを切る。 = plain style
• 玉ねぎを切ります。 = polite style

The ます form is what learners often see first because it is useful and polite in everyday conversation.

By itself, 玉ねぎ does not clearly mark singular or plural.

So depending on context, it could mean:

• an onion
• onions
• the onion
• onion as a general ingredient

Japanese often leaves number unstated unless it matters.

If you want to be more specific, you can add a counter:

• 玉ねぎを一個切ります。 = cut one onion
• 玉ねぎを二個切ります。 = cut two onions

Japanese does not use articles like a or the, and it usually does not mark plurals the way English does.

So 玉ねぎ can be understood from context.

That means English translations may vary:

• Mother cuts an onion in the kitchen.
• Mother cuts the onion in the kitchen.
• Mother cuts onions in the kitchen.

All of these can match the same Japanese sentence, depending on the situation.

Yes, Japanese word order is somewhat flexible, as long as the particles make the roles clear.

For example, these are still understandable:

• 母は玉ねぎを台所で切ります。
• 台所で母は玉ねぎを切ります。

Because the particles show the function of each part:

• は = topic
• で = place of action
• を = object

However, the verb still usually comes at the end, and the original order is very natural for learners to follow.

No. Normal Japanese writing usually does not use spaces between words.

So this sentence would normally be written as:

母は台所で玉ねぎを切ります。

Textbooks often add spaces for beginners so it is easier to see the parts of the sentence. That is helpful for learning, but it is not how Japanese is usually written in real life.
