Legen hjelper henne å føde.

Legen is the definite singular form of lege, so it means the doctor.

• en lege = a doctor
• legen = the doctor

Norwegian often marks the by adding an ending to the noun instead of using a separate word.

Because henne is the object form of hun, just like her is the object form of she in English.

• Hun hjelper. = She helps.
• Legen hjelper henne. = The doctor helps her.

So after the verb hjelper, you need henne, not hun.

Hjelper is the present tense of å hjelpe.

• å hjelpe = to help
• hjelper = helps / is helping

In Norwegian, the present tense often ends in -r. Also, Norwegian present tense can cover both English helps and is helping, depending on context.

Å is the infinitive marker, like English to in to give birth.

So:

• å føde = to give birth

After hjelpe, Norwegian commonly uses an infinitive:

• hjelper henne å føde = helps her give birth / helps her to give birth

With hjelpe, it is also possible to omit å:

• Legen hjelper henne føde.

That is also grammatical, but the version with å is very common and a good default for learners.

Here, å føde means to give birth.

It can be used without an object, as in this sentence, where the focus is simply on the act of giving birth.

It can also be used with an object:

• Hun fødte en sønn. = She gave birth to a son.

So in Legen hjelper henne å føde, the doctor is helping her, and she is the one doing the action føde.

Yes, it is natural and grammatical.

Legen hjelper henne å føde is a clear everyday way to express that idea.

There are also more specific or formal ways to say something similar, for example:

• Legen hjelper henne under fødselen. = The doctor helps her during labor/the birth.
• Legen forløser henne. = The doctor delivers the baby / assists her in childbirth.

So your sentence is perfectly fine, but Norwegian also has more medical-sounding alternatives.

Usually no, not when the mother is the subject.

In Norwegian:

• Hun føder. = She is giving birth.

In English, the mother usually gives birth, while the doctor or midwife delivers the baby.

That means Norwegian and English divide the idea a bit differently. In this sentence, henne å føde means her giving birth, not her delivering.

The structure is:

subject + verb + object + infinitive

So here:

• Legen = subject
• hjelper = verb
• henne = object
• å føde = infinitive phrase

This is normal Norwegian word order in a main clause.

If you move another element to the front, the verb still stays in second position:

• I dag hjelper legen henne å føde. = Today the doctor is helping her give birth.

That verb-second pattern is very important in Norwegian.

A rough English-friendly guide:

• legen ≈ LAY-gən
• føde ≈ something like FUR-duh, but with a vowel English does not really have

The hardest part is ø in føde. To make it, try rounding your lips while saying a vowel somewhat like e in her or a in bird. It is only an approximation, but it can help.

Also, å is pronounced like a long o-type sound, not like the English letter name A.
