Matresterna är till djuret.

Matresterna means the food scraps or the leftovers.

The basic form is en matrest = a food scrap / a leftover.

Its forms are:

• en matrest = a food scrap
• matrester = food scraps
• matresterna = the food scraps

So the ending -na marks definite plural.

Because Swedish usually puts the at the end of the noun as a suffix.

So:

• matresterna = the food scraps
• djuret = the animal

This is very normal in Swedish. English uses a separate word (the), but Swedish often builds definiteness into the noun itself.

Är is the present tense of vara, which means to be.

So:

• är = is / are

In this sentence, it links the subject matresterna with the phrase till djuret.

A useful thing to remember is that Swedish does not change this verb for singular and plural the way English does:

• Djuret är... = The animal is...
• Matresterna är... = The leftovers are...

In both cases, Swedish uses är.

Djuret means the animal.

The basic noun is ett djur = an animal.
Because djur is an ett-word (a neuter noun), its definite singular form ends in -et:

• ett djur = an animal
• djuret = the animal

So -et here is the definite ending for this noun.

Yes, till often means to, but it can also mean for, especially in the sense of intended for, meant for, or going to someone or something.

So Matresterna är till djuret means that the food scraps are for the animal.

A similar pattern is:

• Den här är till dig. = This one is for you.

So till does not only show movement; it can also show the intended recipient.

Yes, often you could.

För is also a common way to say for in Swedish, and in many everyday contexts Matresterna är för djuret would sound natural.

A simple way to think about the difference is:

• till often suggests assigned to / intended for / going to
• för is a more general for

In real life, the difference is often small here, and both can be understandable.

Because the sentence is talking about specific leftovers and a specific animal.

So the idea is not just food scraps in general or an animal in general, but rather:

• the leftovers
• the animal

This usually means the listener already knows which leftovers and which animal are being talked about.

If the animal were not specific, you could say ett djur instead of djuret.

It is plural.

You can tell from the form:

• matrest = singular
• matrester = plural
• matresterna = definite plural

So even though English might sometimes treat leftovers as a kind of general mass idea, in Swedish this word is clearly plural here.

Yes. This is a completely normal Swedish main clause:

• Matresterna = subject
• är = verb
• till djuret = prepositional phrase

So the structure is basically:

Subject + verb + complement

That looks similar to English here.

Also, Swedish main clauses follow the verb-second rule, and this sentence fits that rule perfectly because the verb är comes in the second position.

Yes, it is understandable and grammatically fine.

Depending on the situation, some speakers might also say:

• Matresterna är för djuret.
• Matresterna är till för djuret.

But Matresterna är till djuret is not wrong. It gives the sense that the leftovers are intended for the animal.
