Hon delegerar uppgiften till medarbetaren.

Hon is the subject form of she, so it is used because she is the person doing the action.

• Hon = she
• Henne = her

So in this sentence, hon is correct because she is the one who delegates the task.

Compare:

• Hon delegerar uppgiften. = She delegates the task.
• Jag ser henne. = I see her.

Delegerar is the present tense form of the verb delegera.

For many Swedish verbs that end in -a in the infinitive, the present tense ends in -ar:

• delegera = to delegate
• delegerar = delegates / is delegating

This is a very common pattern in Swedish.

A few useful forms:

• att delegera = to delegate
• delegerar = delegate(s)
• delegerade = delegated
• har delegerat = has/have delegated

Because uppgiften is the definite form: the task.

In Swedish, the definite article is usually added to the end of the noun instead of being a separate word like the in English.

• en uppgift = a task
• uppgiften = the task

So uppgift by itself would mean just task in dictionary form, not the task.

Because Swedish usually puts the definite article on the noun as a suffix.

So:

• uppgiften = the task
• medarbetaren = the coworker / the employee

This is one of the biggest differences from English.

Compare:

• English: the task

• Swedish: uppgiften

• English: the coworker
• Swedish: medarbetaren

A separate definite word can appear in some situations, especially with adjectives:

• den nya uppgiften = the new task

But in your sentence there is no adjective, so the ending alone is enough.

Because the sentence refers to a specific coworker/employee: the coworker, not a coworker.

• en medarbetare = a coworker / an employee
• medarbetaren = the coworker / the employee

So the sentence means that the task is delegated to a particular person, not just any employee.

Till means to here and shows the direction of the delegation: who receives the task.

So the structure is:

• delegerar något till någon
• delegates something to someone

In this sentence:

• uppgiften = the thing being delegated
• till medarbetaren = to the coworker / employee

So till links the task to the recipient.

Usually, till is the most natural choice with delegera.

• delegera uppgiften till medarbetaren = standard, idiomatic Swedish

Using åt would sound less natural here for many speakers. In Swedish, some verbs strongly prefer certain prepositions, and delegera ... till någon is the normal pattern to learn.

So for a learner, the safest choice is:

• delegera något till någon

The sentence follows a very common Swedish pattern:

Subject + verb + object + prepositional phrase

Here that is:

• Hon = subject
• delegerar = verb
• uppgiften = object
• till medarbetaren = prepositional phrase

So:

Hon delegerar uppgiften till medarbetaren.

This is similar to normal English word order: She delegates the task to the employee.

Yes. Swedish follows the V2 rule in main clauses, which means the finite verb usually stays in the second position.

For example:

• Hon delegerar uppgiften till medarbetaren.
• I dag delegerar hon uppgiften till medarbetaren.

Notice what changed:

• When I dag comes first,
• the verb delegerar still stays second,
• and hon moves after the verb.

This is very important in Swedish word order.

It is an en word:

• en medarbetare = an employee / a coworker
• medarbetaren = the employee / the coworker

That is why the definite singular ending is -n:

• medarbetare
  • -n = medarbetaren

The same applies to uppgift:

• en uppgift
• uppgiften

So both nouns in the sentence are en words.

This is a feature of some Swedish nouns. Medarbetare belongs to a group where the singular indefinite and plural indefinite have the same form.

• en medarbetare = an employee
• flera medarbetare = several employees

Then:

• medarbetaren = the employee
• medarbetarna = the employees

This can feel strange to English speakers at first, but it is a normal Swedish pattern.

You add inte after the finite verb in a main clause:

• Hon delegerar inte uppgiften till medarbetaren.

That means: She does not delegate the task to the employee.

This placement is very typical in Swedish:

• subject
• verb
• inte
• rest of sentence

The main thing to notice is that the definite ending -en is added, but the stress stays on the main part of the word:

• uppgift
• uppgiften

The word is roughly pronounced with stress near the beginning, and the -en is an unstressed ending.

A learner should also notice that Swedish often reduces unstressed endings, so the final -en may sound lighter than an English speaker expects.

It can mean both, depending on context.

Medarbetare often means:

• employee
• staff member
• coworker / colleague

In workplace Swedish, it is often used in a slightly professional or organizational way, especially for someone who works under or within a team or company structure.

So in this sentence, medarbetaren could be understood as:

• the employee
• the coworker
• the staff member

The best English translation depends on the situation.
