Boli me noga.

Because boli agrees with noga (leg), which is the thing that hurts.

In Serbian, this sentence is built more like:

The leg hurts me.

So:

• boli = it hurts
• me = me
• noga = leg

A learner may expect something like I hurt in the leg, but Serbian uses a different structure. The body part is treated as the subject of the verb.

Me is the accusative form of ja (I / me).

In Boli me noga, me means me as the person affected by the pain.

Some pronoun forms:

• ja = I
• mene / me = me

Here, the short unstressed form me is used, which is normal in this kind of sentence.

Because noga is the grammatical subject of the sentence.

Even though in English we think of I as the main person in My leg hurts, Serbian structures it as:

Leg hurts me.

That is why noga stays in the nominative singular:

• noga = leg

If it were in another case, the meaning or grammar would change.

Yes, that is the closest literal breakdown.

Word by word:

• boli = hurts
• me = me
• noga = leg

Natural English translation:

• My leg hurts
• My leg is hurting

So the Serbian sentence does not use my directly here. Instead, it uses me to show whose leg is affected.

Because with body parts, Serbian often avoids using possessives like my, your, etc. when the meaning is already clear.

So instead of saying:

• Moja noga boli or Moja noga me boli

Serbian more naturally says:

• Boli me noga

This is very common with body parts:

• Boli me glava = My head hurts
• Boli me ruka = My arm hurts
• Bole me leđa = My back hurts

Using moja is possible in some contexts, especially for emphasis or contrast, but it is usually not the most neutral everyday wording.

Yes, Noga me boli is also correct.

Serbian word order is more flexible than English. The most neutral versions are often:

• Boli me noga
• Noga me boli

The difference is usually about focus or emphasis:

• Boli me noga can sound like the pain is the main point.
• Noga me boli can put more focus on the leg.

In everyday speech, both are common and natural.

You would say:

Bole me noge.

Why?

• noge is plural of noga
• the verb must agree with the plural subject
• so boli becomes bole

Compare:

• Boli me noga = My leg hurts
• Bole me noge = My legs hurt

This same pattern appears with other body parts:

• Boli me ruka = My arm hurts
• Bole me ruke = My arms hurt

No, those are not correct.

Why not:

• Bolim would mean I hurt, but that is not how Serbian expresses this idea.
• Bolim me noga mixes forms incorrectly.

The standard pattern is:

Boli/Bole + object pronoun + body part

Examples:

• Boli me glava = My head hurts
• Boli te stomak = Your stomach hurts
• Bole ga oči = His eyes hurt

So for My leg hurts, the correct sentence is:

• Boli me noga

Yes. The verb is boleti, meaning to hurt / to ache.

In this sentence:

• boli = 3rd person singular present
• it matches noga, which is singular

Some forms:

• boli = it hurts
• bole = they hurt

Examples:

• Boli me zub = My tooth hurts
• Bole me oči = My eyes hurt

Because Serbian has no articles.

English uses:

• the leg
• a leg

Serbian just says:

• noga

Whether it means a leg, the leg, or just leg depends on context.

So in Boli me noga, noga is understood naturally as my leg because of the situation and the pronoun me.

You would usually say:

• Bolela me noga if the speaker is male or female? Wait, careful: the participle agrees with the subject noga, not with the speaker.

Since noga is feminine singular, the form is:

• Bolela me noga = My leg hurt / My leg was hurting

Compare:

• Boli me noga = My leg hurts
• Bolela me noga = My leg hurt

Again, the verb form agrees with noga, not with me.

Yes, many. This is a very common Serbian pattern for pain and body discomfort.

Examples:

• Boli me glava = My head hurts
• Boli me stomak = My stomach hurts
• Boli me ruka = My arm hurts
• Boli me zub = My tooth hurts
• Bole me oči = My eyes hurt
• Bole me leđa = My back hurts

So once you understand Boli me noga, you can use the same structure with many other body parts.
