Min chef vil have svaret senest klokken tre i eftermiddag.

In Danish, chef means boss, manager, or head of something.

So min chef means my boss.

If you mean a cook or a chef in the English food sense, the usual Danish word is kok.

Examples:

• min chef = my boss
• en kok = a cook

Because chef is a common gender noun in Danish, not a neuter noun.

Danish possessives change according to the gender and number of the noun:

• min for singular common gender
• mit for singular neuter
• mine for plural

So:

• en chef → min chef
• et svar → mit svar
• flere svar → mine svar

In Danish, a possessive such as min, din, hans, vores, etc. normally replaces the article.

So you say:

• min chef = my boss

Not:

• min chefen

This works like English:

• my boss not
• my the boss

Yes, vil can often correspond to English will, but it also very often means want to or be willing to.

In this sentence, vil is best understood as wants:

• Min chef vil have svaret = My boss wants the answer

So this is not mainly about the future. It is about your boss’s wish or requirement.

Because after a modal verb like vil, Danish uses the infinitive form of the next verb.

So:

• vil have
• kan komme
• skal gå
• må vente

Not:

• vil har
• kan kommer
• skal går

That is similar to English:

• wants to have
• can come
• must go

Although Danish often leaves out at in this kind of structure after modal verbs.

Here, svaret is the noun svar in the definite singular form.

• et svar = an answer
• svaret = the answer

So the phrase means:

• have svaret = have the answer

This is one of the most important things to notice in the sentence.

Because svar is a neuter noun.

The pattern is:

• indefinite singular: et svar
• definite singular: svaret

For many neuter nouns, the definite singular ending is -et.

Other examples:

• et hus → huset
• et brev → brevet

So:

• et svar → svaret

It can look that way, because svaret is also the past participle form connected with the verb svare in some contexts.

For example:

• Jeg har svaret = I have answered

But in this sentence, the natural reading is clearly the noun:

• Min chef vil have svaret = My boss wants the answer

Why? Because the whole sentence is about receiving or having the answer by a deadline. That makes much more sense here than reading svaret as a verb form.

Senest means at the latest or no later than.

In natural English, with a deadline, it is often best translated as by:

• senest klokken tre = by three o’clock
• literally: at the latest at three o’clock

So senest tells you the latest acceptable time.

Klokken is commonly used before clock times in Danish.

So:

• klokken tre = three o’clock
• klokken otte = eight o’clock

It is the normal, natural way to give a specific time.

In some contexts, Danish speakers may shorten things, but klokken tre is the standard full expression here.

Because i eftermiddag means this afternoon or this afternoon at some point, referring to a specific afternoon close to now.

So:

• i eftermiddag = this afternoon

By contrast:

• om eftermiddagen usually means in the afternoon in a general or habitual sense

Examples:

• Vi ses i eftermiddag = We’ll see each other this afternoon
• Jeg arbejder ofte om eftermiddagen = I often work in the afternoon

So in your sentence, i eftermiddag is the right choice because it refers to today’s afternoon.

No, this is normal main-clause word order.

The structure is:

• Min chef = subject
• vil = finite verb
• have = infinitive
• svaret = object
• senest klokken tre i eftermiddag = time expression

So the sentence follows the usual Danish pattern where the finite verb comes early in the clause.

If you move another element to the front, then the subject usually moves after the finite verb:

• Senest klokken tre i eftermiddag vil min chef have svaret

That is also correct, but the original sentence is the most straightforward version.
