tā de tǐlì gòu.

Literally, it is something like:

• 她 = she
• 的 = possessive marker, like ’s or of
• 体力 = physical strength, stamina, physical energy
• 够 = enough, sufficient

So the literal structure is:

Her physical strength is enough.

In natural English, this often means:

• She has enough stamina.
• Her strength is sufficient.
• She’s physically strong enough.

The exact translation depends on the situation.

的 links 她 to 体力 and shows possession or association.

So:

• 她的体力 = her physical strength/stamina

This is very similar to English her stamina.

A few comparisons:

• 她的书 = her book
• 她的朋友 = her friend
• 她的体力 = her physical strength

In this sentence, 的 is necessary because 她 is modifying the noun 体力.

体力 usually means physical strength, stamina, or physical energy.

It refers to the body’s ability to keep going physically, not mental ability.

For example, it can be used when talking about:

• exercising
• working hard
• walking long distances
• doing something physically demanding

It is different from things like:

• 精力 = energy, often more general or mental/overall energy
• 力量 = force, strength, power
• 耐力 = endurance

So 体力够 suggests that her body has enough strength or stamina for something.

Here, 够 means to be enough or to be sufficient.

So 体力够 means:

• the stamina is enough
• the physical strength is sufficient

A very important point: 够 often implies enough for something, and that something may be omitted if it is already clear from context.

For example:

• 她的体力够。 = Her stamina is enough.
  
  • enough for the task, race, trip, etc.

You will also often see fuller versions such as:

• 她的体力够了。 = Her stamina is enough now / that’s enough stamina.
• 她的体力够不够？ = Is her stamina enough?
• 她的体力够跑完全程。 = Her stamina is enough to finish the whole race.

So in your sentence, 够 is short and context-dependent.

It is understandable, but by itself it can sound a little clipped or context-dependent.

Native speakers often say this kind of sentence when the missing idea is obvious from the situation. For example, if people are discussing whether she can complete a hike, someone may say:

• 她的体力够。

That means:

• Her stamina is enough.

In many situations, more natural versions might be:

• 她的体力够了。
• 她体力够。
• 她的体力足够。
• 她有足够的体力。

So yes, the sentence works, but it sounds most natural when the context already tells you enough for what.

Because 够 is acting like a predicate here, so you do not need 是.

In Chinese, 是 is not used before every adjective or descriptive predicate. This is a very common point for English speakers, because English often uses to be.

Compare:

• 她很累。 = She is tired.
• 天气很冷。 = The weather is cold.
• 她的体力够。 = Her stamina is enough.

Not:

• 她的体力是够。 ← unnatural in standard usage

So think of 够 here as directly describing the subject.

Yes. 她体力够 is also possible and often sounds quite natural in speech.

Difference:

• 她的体力够 focuses more clearly on her stamina
• 她体力够 is a bit more compact and conversational

Both can mean essentially the same thing in the right context.

Chinese often allows this kind of flexibility when talking about a person and one of their qualities or conditions.

For a learner, it is good to recognize both patterns:

• 她的体力够。
• 她体力够。

The pronunciation is:

• 她 = tā (first tone)
• 的 = de (neutral tone here)
• 体力 = tǐlì (third tone + fourth tone)
• 够 = gòu (fourth tone)

A few notes:

• 她 sounds the same as 他 and 它 in spoken Mandarin: all are tā
• 的 is usually light and unstressed here
• 体 is third tone, so keep it low/dipping
• 够 is a strong falling fourth tone

So the whole sentence sounds roughly like:

tā de tǐlì gòu

They are close, but not always identical in style.

• 够 = enough, sufficient
• 足够 = sufficient, enough, often a bit more explicit or formal

Examples:

• 她的体力够。
• 她的体力足够。

Both mean her stamina is sufficient, but 足够 can sound slightly more complete or formal.

You may also see:

• 她有足够的体力。 = She has enough stamina.

That structure is very common and often especially clear for learners.

Usually, Chinese leaves out information that is obvious from context. After 够, the omitted idea is often something like:

• for the race
• for the job
• to finish it
• to carry this
• to keep going

So depending on context, 她的体力够 might really mean:

• Her stamina is enough for the climb.
• She has enough physical strength to do it.
• Her energy will be enough.

Chinese often avoids repeating information when everyone already knows what is being discussed.

Yes, very easily. Some common ways are:

• 她的体力够吗？ = Is her stamina enough?
• 她的体力够不够？ = Is her stamina enough or not?
• 她有足够的体力吗？ = Does she have enough stamina?

Among these, 够不够 is especially common in everyday speech because it directly asks whether something is sufficient.

Yes, 体力 is a noun.

The sentence structure is:

她的体力 + 够

That is:

• subject/topic: 她的体力 = her stamina
• predicate: 够 = is enough

So the whole sentence is a simple subject-predicate sentence.

You can think of it as:

• [Her stamina] [is sufficient].

This is one of the very common Chinese patterns where a noun phrase is followed directly by a descriptive word or predicate, without needing a separate word like is.
