Jag är mätt efter middagen.

Because Swedish expresses this idea with to be + an adjective, not to have.

• Jag är mätt = literally I am full/satisfied from food
• English also says I am full, so this matches that pattern more closely than I have...

Using har here would sound wrong for this meaning.

Mätt means full, satiated, or no longer hungry after eating.

It specifically refers to food. So:

• Jag är mätt = I’m full
• It does not mean emotionally satisfied in most ordinary cases

A useful contrast is:

• hungrig = hungry
• mätt = full

Because adjectives in Swedish change form depending on what they describe.

Here, mätt is the form used with jag in this sentence:

• Jag är mätt = I am full

Compare:

• Han är mätt = He is full
• Hon är mätt = She is full
• Barnet är mätt = The child is full
• Vi är mätta = We are full

So the plural form is mätta, while the singular predicative form here is mätt.

It is a prepositional phrase:

• efter = after
• middagen = the dinner / dinner

Together:

• efter middagen = after dinner

It tells us when the speaker is full.

So the structure is:

• Jag = I
• är = am
• mätt = full
• efter middagen = after dinner

Because -en is the definite article attached to the noun.

In Swedish, the definite article is usually added as a suffix:

• en middag = a dinner
• middagen = the dinner / the dinner meal

In expressions like efter middagen, Swedish often uses the definite form where English simply says after dinner.

So even though English has no the here, Swedish commonly does.

Usually in modern standard Swedish in Sweden, middag means dinner, often the main meal of the day.

But there is a detail learners often notice:

• historically, middag is related to midday
• in some dialects, regions, or older usage, it can refer to the midday meal

Still, for most learners of modern standard Swedish, middag is safest to understand as dinner.

Usually no, unless you want a very different meaning.

In Swedish:

• mätt = full from food
• full = drunk

So:

• Jag är mätt efter middagen = I’m full after dinner
• Jag är full efter middagen = I’m drunk after dinner

That is a very important difference.

Yes, you can.

Both are correct:

• Jag är mätt efter middagen.
• Efter middagen är jag mätt.

The second version puts more focus on after dinner.

This also shows a basic Swedish word-order rule: if you start with something other than the subject, the verb still comes second.

So:

• Efter middagen = first position
• är = second position
• jag = comes after the verb

In normal use, it strongly suggests both:

• after dinner in time
• and naturally because of dinner

So efter middagen mainly gives the time frame, but the meaning also implies the dinner caused that feeling.

If you wanted to stress the cause more directly, Swedish could also use other wording, for example:

• Jag blev mätt av middagen. = I got full from the dinner.

But Jag är mätt efter middagen is a very natural everyday sentence.

A rough guide is that it sounds something like mett, but with a short vowel and a strong final t sound.

A few pronunciation notes:

• ä is not exactly like English a or e
• the vowel is short here
• the double tt shows that the vowel before it is short

So try to keep mätt short and clipped, not stretched out.

Yes, absolutely.

• Jag är mätt. = I’m full.

Adding efter middagen just gives extra context:

• Jag är mätt efter middagen. = I’m full after dinner.

If the context is already clear, Swedish speakers would very often just say Jag är mätt.
