Má ég fá að smakka sósuna áður en þú setur hana á pastað?

Má ég means May I or Am I allowed to.

It comes from the verb mega, which is used for permission or possibility.

• Má ég fara? = May I go?
• Má ég spyrja? = May I ask?

In this sentence, Má ég is a polite way to ask for permission.

The construction fá að + infinitive often means to get to do something or to be allowed to do something.

So:

• Má ég smakka sósuna? = May I taste the sauce?
• Má ég fá að smakka sósuna? = literally May I get to taste the sauce?

The version with fá að can sound a bit softer or more polite, depending on context. It is very natural Icelandic.

Because smakka is the infinitive, to taste.

After að in the construction fá að + infinitive, Icelandic uses the infinitive form:

• fá að smakka = get to taste
• fá að borða = get to eat
• fá að sjá = get to see

If you said smakkar, that would be a finite verb form, like taste / are tasting, and it would not fit after að here.

Sósuna is the sauce in the accusative singular.

The base noun is:

• sósa = sauce

Its definite form in the nominative is:

• sósan = the sauce

But because it is the direct object of smakka (taste something), it appears in the accusative:

• smakka sósuna = taste the sauce

So the ending changes because Icelandic marks case.

Hana means it/her in the accusative singular feminine.

It refers back to sósuna / sósan, which is a feminine noun. In Icelandic, pronouns must agree with the grammatical gender of the noun they refer to.

So:

• sósa is feminine
• therefore hana is used

Compare:

• Ég sé sósuna. Ég smakka hana.
  I see the sauce. I taste it.

Even though English uses it, Icelandic uses the form that matches the noun’s gender.

Áður en means before in the sense of before something happens.

It introduces a clause:

• áður en þú setur hana á pastað
  = before you put it on the pasta

You can think of it as:

• áður = earlier / before
• en = than / before introducing the clause

This is a very common expression in Icelandic.

Examples:

• Borðaðu áður en þú ferð. = Eat before you go.
• Hringdu í mig áður en þú kemur. = Call me before you come.

Icelandic often uses the present tense where English uses a future meaning.

So:

• áður en þú setur hana á pastað
  literally: before you put it on the pasta

Even though the action has not happened yet, Icelandic normally uses the present tense in this kind of subordinate clause.

This is very natural and common.

That part is a subordinate clause introduced by áður en.

The basic order is:

• þú = subject
• setur = verb
• hana = object
• á pastað = prepositional phrase

So it follows a straightforward pattern:

subject + verb + object + place/direction

In main clauses, Icelandic often has verb-second word order, but subordinate clauses are usually more straightforward.

Because á can take either accusative or dative, depending on meaning.

Here, setja hana á pastað means put it onto/on the pasta — there is movement or placement toward a surface/resulting position. That usually takes the accusative.

So:

• á pastað = onto the pasta / on the pasta with placement

By contrast, the dative often refers more to location:

• á pastanu = on the pasta as a location/state

This accusative-vs-dative distinction with prepositions is very important in Icelandic.

Pastað is accusative singular definite of the neuter noun pasta.

Forms are:

• pasta = pasta
• pastað = the pasta

In this sentence it is accusative because it follows á in a directional/placement sense:

• setja hana á pastað = put it on the pasta

So both the meaning of the preposition and the structure of the sentence affect the case.

Þú is completely normal in modern Icelandic.

Icelandic generally uses þú even in many situations where English might use more formal wording. There is no everyday formal you equivalent like French vous or German Sie.

So this sentence is polite because of the wording:

• Má ég...
• fá að...

—not because of a special formal pronoun.

Yes, absolutely.

That version is also natural and means essentially the same thing:

• Má ég smakka sósuna... = May I taste the sauce...
• Má ég fá að smakka sósuna... = May I get to taste the sauce...

The version with fá að can sound a bit more tentative or polite, but both are good Icelandic.

The sentence breaks down like this:

• Má ég = May I
• fá að smakka sósuna = get to taste the sauce
• áður en = before
• þú setur hana á pastað = you put it on the pasta

So the full structure is:

permission question + infinitive phrase + time clause

That makes it a very useful pattern for learners:

• Má ég fá að sjá þetta? = May I see this?
• Má ég fá að prófa þetta áður en þú kaupir það? = May I try this before you buy it?
