zhè shì tā de qīzi.

Yes, the basic order is very similar to English in this sentence:

• 这 = this
• 是 = is
• 他 的 妻子 = his wife

So the structure is:

this + is + his wife

That makes this a very beginner-friendly sentence because the word order matches English quite closely.

的 is a very common particle that links a possessor to a noun. Here it works like the English possessive 's or words like his/her.

So:

• 他 = he / him
• 他的 = his
• 妻子 = wife

Together, 他的妻子 means his wife.

A useful pattern to remember is:

noun/pronoun + 的 + noun

Examples:

• 我的书 = my book
• 她的老师 = her teacher
• 他们的家 = their home

Usually, learners should keep 的 here: 他的妻子.

In Mandarin, 的 is sometimes omitted in close relationships or very common expressions, especially with family terms, for example:

• 我妈 = my mom
• 我爸爸 = my dad

With 妻子, omission is possible in some styles, especially formal or written language, such as 他妻子, but for most learners 他的妻子 is the safest and most standard choice.

So the simple rule is:

• Use 的 unless you already know omission is natural.

这 can mean this or this one by itself when the context is clear.

In 这是他的妻子, 这 means something like:

• this
• this person
• this one

Mandarin often leaves out words that are obvious from context. If you are introducing someone, 这 alone is perfectly natural.

You could also hear:

• 这是我朋友。
• 这是王老师。

So 这 does not need an extra noun here.

是 is the verb to be when linking one noun or pronoun to another noun.

In this sentence, it links:

• 这
  and
• 他的妻子

So it works like is in English.

This is a common pattern:

A 是 B

Examples:

• 这是老师。
• 他是学生。
• 那是我哥哥。

However, Mandarin does not always use 是 where English uses to be. For example, with adjectives:

• 她很漂亮。 = She is pretty.
  Not: 她是漂亮。

So 是 is mainly used to connect nouns, not adjectives.

Both 这 and 是 have the fourth tone, so they are said with a falling tone.

• 这 = zhè
• 是 = shì

A few pronunciation notes:

• zh in zhè is a retroflex sound, with the tongue curled slightly back.
• sh in shì is also retroflex.
• The i in shì is not pronounced exactly like English ee. It is a special Mandarin vowel sound after sh.

Since both are fourth tone, learners often make the sentence too flat. Make sure they fall clearly:

• zhè
• shì

Yes. In spoken Mandarin:

• 他 = he
• 她 = she

Both are pronounced tā.

The distinction is clear in writing, but not in speech. Native speakers understand from context.

So if you hear tā de qīzi, you know tā refers to someone whose wife is being discussed, and context tells you whether that person is male or female, if it matters.

This same thing happens with:

• 它 = it
  also pronounced tā

妻子 is correct and fairly neutral, but it can sound a bit formal or written compared with some everyday alternatives.

Common words include:

• 妻子 = wife, somewhat formal/neutral
• 老婆 = wife, very common in everyday speech, more colloquial
• 太太 = wife / Mrs., polite, but usage depends on region and context
• 爱人 = spouse, used in some contexts and regions

So 他的妻子 is perfectly correct, especially in textbook Mandarin. In daily conversation, people may also say 他老婆.

Yes, mainly in tone and style.

• 妻子 sounds more neutral, formal, or written.
• 老婆 sounds more conversational and common in daily speech.

For example:

• 这是他的妻子。
  This sounds correct and standard.

• 这是他老婆。
  This sounds more casual and spoken.

As a learner, 妻子 is a good word to know because it is clear and widely accepted.

Measure words are used in Mandarin when a noun is counted or modified by a number or demonstrative in many cases, such as:

• 一个人
• 这本书

But here, 妻子 is not being counted. It is the noun after 是, functioning as the predicate noun. So no measure word is needed.

You are not saying:

• this one wife

You are saying:

• This is his wife

That is why 这是他的妻子 does not use a measure word.

No. Standard written Chinese does not normally use spaces between words.

So the normal written form is:

这是他的妻子。

The spaced version:

这 是 他 的 妻子

is only used for teaching, to help learners see the parts more clearly.

Yes. The grammar is the same.

• 这 = this
• 那 = that

So:

• 这是他的妻子。 = This is his wife.
• 那是他的妻子。 = That is his wife.

Use 这 for something or someone closer, and 那 for something or someone farther away, or less immediate in the context.

Yes, it is natural and correct, especially in a clear textbook-style introduction.

For example, if you are pointing someone out in a photo or introducing people, this works well.

In real conversation, native speakers might also say things like:

• 这位是他的妻子。
• 这是他太太。
• 这是他老婆。

Adding 位 can make it sound a little more polite when introducing a person:

• 这位是他的妻子。 = This is his wife.

But your sentence is already completely correct.
