Min nabo er meget hjælpsom og pålidelig, så jeg kan altid bede hende om hjælp.

Because nabo is a common-gender noun in Danish.

Danish singular nouns usually take:

• en for common gender
• et for neuter

Since it is en nabo, the possessive is:

• min nabo = my neighbor

Compare:

• min ven = my friend
• mit hus = my house

So the possessive has to match the noun’s gender.

These adjectives are used predicatively, meaning they come after er and describe the subject.

In Danish, predicative adjectives often appear in their basic form with a common-gender singular subject:

• Naboen er hjælpsom
• Hun er pålidelig

Since min nabo is singular and common gender, the base forms hjælpsom and pålidelig are correct.

You would see other forms in different situations, for example:

• et hjælpsomt barn = a helpful child
• hjælpsomme naboer = helpful neighbors

Meget means very here.

It strengthens the adjective, just like English very:

• meget hjælpsom = very helpful
• meget pålidelig = very reliable

So meget is an adverb modifying the adjectives.

Because Danish often uses a comma to separate clauses.

Here the sentence has two parts:

1. Min nabo er meget hjælpsom og pålidelig
2. så jeg kan altid bede hende om hjælp

The comma helps mark the transition to the result/consequence:

• My neighbor is very helpful and reliable, so...

Comma rules in Danish can be a bit different from English, but this kind of comma is very normal.

Here så means so or therefore.

It connects the first idea to the second:

• My neighbor is very helpful and reliable, so I can always ask her for help.

It shows a result:

• because she is helpful and reliable,
• therefore I can ask her for help.

Because after a modal verb like kan (can), Danish uses the infinitive without at.

So:

• jeg kan bede = I can ask
• jeg vil hjælpe = I want to help
• jeg skal gå = I must go

You use at with many infinitives, but not after modal verbs such as:

• kan
• vil
• skal
• må
• burde

Because in Danish, adverbs like altid often come after the finite verb and before the infinitive/main verb.

Here:

• jeg kan altid bede hende om hjælp

Breakdown:

• jeg = subject
• kan = finite verb
• altid = adverb
• bede = infinitive/main verb

This is very typical Danish word order.

Compare:

• Jeg kan altid komme senere.
• Hun vil ofte hjælpe.

Because hende is the object form of hun.

Use:

• hun = she (subject)
• hende = her (object)

In this sentence, she is the person being asked, so Danish uses the object form:

• jeg kan altid bede hende om hjælp
• literally: I can always ask her for help

Compare:

• Hun hjælper mig. = She helps me.
• Jeg hjælper hende. = I help her.

The verb bede often uses the pattern:

bede nogen om noget
= ask someone for something

So:

• bede hende om hjælp = ask her for help

Breakdown:

• bede = ask
• hende = her
• om hjælp = for help

This is a very common structure in Danish:

• Jeg bad ham om penge. = I asked him for money.
• Hun bad mig om råd. = She asked me for advice.

Yes, but there is a slight difference in feel.

• bede nogen om hjælp = ask someone for help / request help
• spørge nogen om hjælp = ask someone for help

In many situations both are possible, but bede om hjælp often sounds a bit more like requesting assistance, while spørge om hjælp can sound a bit more like asking/inquiring.

So in this sentence, bede hende om hjælp is very natural.

Because hjælp is being used in a general, uncountable sense here.

So:

• om hjælp = for help

This works like English:

• ask for help not usually
• ask for a help

You could use an article in other contexts, but here the general noun is the normal choice.

No. Nabo itself does not have to be female.

The word nabo can refer to a neighbor in general. What tells you the neighbor is female here is hende:

• hende = her

So the sentence means the speaker’s neighbor is female, but that information comes from the pronoun, not from nabo itself.

It is actually quite close to English:

• Min nabo = My neighbor
• er meget hjælpsom og pålidelig = is very helpful and reliable
• så = so
• jeg kan altid bede hende om hjælp = I can always ask her for help

The biggest differences for an English speaker are usually:

• adjective agreement rules
• word order with kan altid bede
• using hende instead of hun
• the pattern bede nogen om noget

So although the meaning is straightforward, the grammar contains several very typical Danish patterns.
