Esiintyjä hurmasi meidät vielä viimeisellä kappaleella.

Esiintyjä means performer. It comes from the verb esiintyä, which means to perform, to appear, or to go on stage.

In this sentence, esiintyjä is the subject: the person who was performing and charmed us.

A few related words:

• esiintyä = to perform
• esiintyminen = performance
• esiintyjä = performer

Because hurmasi is the past tense form of hurmata, which means to charm, to captivate, or to enchant.

• hurmata = to charm
• hurmasi = charmed

The ending here shows the Finnish imperfect (the basic past tense). So the sentence is talking about something that happened in the past.

Because meidät is the object form of me (we/us).

• me = we
• meidät = us

In this sentence, meidät means us as the target of the action: the performer charmed us.

Finnish often changes the form of a pronoun when it is the object of a verb.

This is a very common Finnish question.

Here, meidät is used because the action is seen as complete or resultative: the performer successfully charmed us. This is called the total object.

Compare:

• Esiintyjä hurmasi meidät. = The performer charmed us.
  The action is completed.
• Esiintyjä hurmasi meitä. = The performer was charming us / charmed us to some extent.
  This sounds more partial, ongoing, or less clearly complete.

So meidät fits well because the sentence describes a finished effect.

Vielä is a flexible word. It can mean things like:

• still
• yet
• even
• in the end / one more time, depending on context

In this sentence, vielä adds the idea that the performer managed to charm us even with the final song or still at the very end.

So the feeling is something like:

• the performer had already impressed us, and then
• even the last song was enough to charm us too

It gives a nice sense of one more impressive moment at the end.

Literally, it means something like on/with the last song.

• viimeisellä = on the last / with the last
• kappaleella = on/with the song, track, or piece

Together, viimeisellä kappaleella means:

• with the last song
• during the last song
• by means of the last song

In natural English, with the last song is usually the best translation.

Because the adjective has to agree with the noun.

The basic forms are:

• viimeinen = last
• kappale = song / piece / track

But in the sentence, the noun is in the adessive case:

• kappaleella

So the adjective changes too:

• viimeisellä kappaleella

This is normal Finnish adjective agreement: the adjective and noun usually match in case and number.

The ending -lla/-llä is the adessive case.

Its core meanings often include:

• on
• at
• with
• using
• by means of

Here it has an instrumental kind of meaning: the performer charmed us with the last song.

So:

• kappaleella = with the song / by means of the song

This is a very natural Finnish way to express the idea.

Because viimeinen is the dictionary form, but in the sentence it must match the case of kappaleella.

Compare:

• viimeinen kappale = the last song
• viimeisellä kappaleella = with the last song

The word viimeinen is one of those adjectives that changes quite a lot when declined:

• viimeinen
• viimeisen
• viimeisellä
• etc.

So viimeisellä is just the correct case form here.

Not always.

Kappale can mean:

• song
• track
• piece
• item
• copy, depending on context

In music, kappale very often means song or track.
So in this sentence, that is the natural interpretation.

Finnish normally does not use articles like the or a/an.

So:

• esiintyjä can mean a performer or the performer
• viimeisellä kappaleella can mean with the last song

The context tells you which one is meant. In this sentence, English naturally uses the:

• The performer charmed us with the last song.

The word order is quite natural and neutral:

Esiintyjä hurmasi meidät vielä viimeisellä kappaleella.

A rough structure is:

• Esiintyjä = subject
• hurmasi = verb
• meidät = object
• vielä viimeisellä kappaleella = adverbial part

Finnish word order is more flexible than English, but changing it changes emphasis.

For example:

• Vielä viimeisellä kappaleella esiintyjä hurmasi meidät.
  This puts more focus on with the last song / at the very end.
• Meidät esiintyjä hurmasi vielä viimeisellä kappaleella.
  This is more marked and gives special emphasis to us.

So the original version sounds normal and smooth.

Yes. That is a useful nuance to notice.

The Finnish form allows a meaning somewhere between:

• during the last song
• with the last song
• by means of the last song

In context, English usually chooses with the last song, because the song is what caused the effect. But Finnish leaves a bit more room for both timing and means at once.

Yes, it is somewhat expressive.

Hurmata is stronger and more colorful than just saying someone was nice or good. It suggests that the performer really captivated, enchanted, or won over the audience.

So the sentence does not just mean the performer sang the last song well. It suggests the performer made a strong positive impression.
