wǒ de yǎnjing hěn lèi.

的 marks possession, so 我的眼睛 means my eyes.

The pattern is:

我 + 的 + 眼睛
= my eyes

In Chinese, 的 is very commonly used between a person and a noun they possess.

With body parts, native speakers sometimes omit 的 in casual speech, especially in certain sentence patterns, but 我的眼睛 is clear, natural, and very safe for learners.

Not always. In sentences like this, 很 often does not need to be translated as a strong very.

In Mandarin, when an adjective like 累 is used as the main predicate, Chinese often adds 很 to make the sentence sound natural and neutral.

So:

我的眼睛很累
usually means
My eyes are tired / My eyes feel tired

If you stress 很, then it can sound more like very tired.

So 很 here is often functioning more like a natural adjective marker than a strongly emphatic very.

Because in Chinese, adjectives can work directly as predicates.

English says:

My eyes are tired.

Chinese says:

我的眼睛很累。

There is no need for a verb like are between eyes and tired.

This is a very important pattern in Mandarin:

• 他很忙。 = He is busy.
• 天气很冷。 = The weather is cold.
• 我的眼睛很累。 = My eyes are tired.

Usually no. That sounds unnatural.

是 is generally not used before an adjective like 累 in this kind of sentence.

So:

• 我的眼睛很累。 = correct
• 我的眼睛是很累。 = usually unnatural

Use 是 mainly when connecting nouns, not adjectives:

• 我是老师。 = I am a teacher.

But with adjectives, you normally just use the adjective directly, often with 很:

• 我很累。
• 眼睛很累。

Usually 眼睛 refers to eyes as a pair, or to the eyes in general.

So in this sentence, 我的眼睛很累 most naturally means:

My eyes are tired.

If you want to talk about just one eye, you would normally specify it:

• 一只眼睛 = one eye
• 左眼 = left eye
• 右眼 = right eye

So 眼睛 here is best understood as eyes.

It is commonly pronounced yǎnjing, with the second syllable often in a neutral tone.

So instead of a strong jīng, learners will often hear something closer to:

yǎn·jing

This is very common in everyday Mandarin.

A rough breakdown:

• 眼 = yǎn
• 睛 in this word is often light/unstressed

This neutral-tone pronunciation helps speech sound more natural.

You can, but it often sounds less neutral and more context-dependent.

Compare:

• 我的眼睛很累。 = natural, neutral statement
• 我的眼睛累。 = possible, but may sound abrupt, contrastive, or incomplete without context

For learners, 我的眼睛很累 is the safest and most natural choice.

Yes, but the meaning changes.

• 我很累。 = I am tired.
• 我的眼睛很累。 = My eyes are tired.

The first sentence means your whole body or overall condition is tired.
The second specifically says your eyes are tired, maybe from reading, screens, or lack of sleep.

So choose depending on what you want to emphasize.

Yes. 累 can describe a person, a body part, or even the feeling of strain from overuse.

So 眼睛很累 is natural and means the eyes feel tired or strained.

Depending on context, English might translate it as:

• My eyes are tired
• My eyes feel tired
• My eyes are strained

If the eyes hurt rather than just feel tired, Chinese might use other words, such as:

• 疼 = hurt / ache
• 酸 = sore
• 不舒服 = uncomfortable

Yes, and it means something slightly different.

• 我的眼睛很累。 = My eyes are tired.
• 我的眼睛累了。 = My eyes have become tired / My eyes are getting tired.

The 了 often suggests a change of state.

So:

• 很累 describes the condition
• 累了 emphasizes that the condition has now happened

Both are common and natural.

No, but it is the most common everyday word.

Other possibilities include:

• 疲劳 = fatigued, strained, more formal
• 疲倦 = tired, somewhat more literary or formal

Examples:

• 我的眼睛很累。 = everyday, natural
• 我的眼睛很疲劳。 = my eyes are fatigued / strained

For normal conversation, 累 is usually the best choice.

The pattern is:

possessor + 的 + body part + 很 + adjective

So this sentence is:

我 + 的 + 眼睛 + 很 + 累

You can use the same pattern with many other adjectives:

• 我的手很冷。 = My hands are cold.
• 我的头很痛。 = My head hurts.
  
  • Though with 痛, you may also hear slightly different patterns.
• 我的脚很酸。 = My feet are sore.

This is a very useful structure for talking about how body parts feel.
