Puella aliquid dulce emere cupit, sed ipsa dicit se reliquos nummos servare debere.

Because aliquid is a neuter singular word meaning something, and dulce agrees with it.

A few useful points:

• aliquid is the neuter form of something / anything
• dulce is the neuter singular form of the adjective dulcis, dulce = sweet
• Since aliquid is neuter singular, the adjective is neuter singular too

So:

• aliquid dulce = something sweet

Even though aliquid is the object of emere, its accusative form is still aliquid, and the neuter accusative singular of dulce is also dulce. So the form is exactly what we expect.

Because Latin often uses an infinitive after verbs like cupit to express wanting to do something.

So:

• cupit = she wants
• emere = to buy

Together:

• emere cupit = she wants to buy

This is very similar to English wants to buy.

Other Latin verbs often work the same way:

• vult venire = he wants to come
• debet laborare = she ought to work
• potest videre = he can see

ipsa adds emphasis. It means she herself or simply she, but with stress.

So the sentence is not just saying:

• sed dicit... = but she says...

It says:

• sed ipsa dicit... = but she herself says...

This can suggest contrast, such as:

• she wants one thing,
• but she herself says something more responsible.

In Latin, forms of ipse, ipsa, ipsum are often used to emphasize a person or thing:

• ipse venit = he himself came
• ipsa vidit = she herself saw
• ipsi hoc fecerunt = they themselves did this

Because after dicit, Latin often uses an indirect statement, and the subject of that indirect statement goes into the accusative.

Here:

• dicit = she says
• se ... servare debere = that she ought to save...

So se is the accusative subject of the infinitives servare and debere.

It is specifically se because it refers back to the subject of dicit, namely the girl. Latin uses se as a reflexive pronoun in this kind of situation.

Compare:

• Puella dicit se venire.
  = The girl says that she is coming.
  Here she means the girl herself.

If Latin used a non-reflexive pronoun, it could mean some other female person instead.

So se is important because it shows that the person doing the saying and the person who ought to save the coins are the same person.

Because Latin usually expresses reported statements with an accusative-and-infinitive construction, not with a word exactly like English that.

In English, we say:

• She says that she ought to save the remaining coins.

In Latin, that becomes:

• dicit se reliquos nummos servare debere

Structure:

• dicit = she says
• se = subject of the reported statement, in the accusative
• servare debere = the verbal idea of the reported statement, in infinitives

This is one of the most important Latin constructions to learn.

A simple example:

• Marcus dicit se laborare.
  = Marcus says that he is working.

Latin does not usually insert a separate word for that here.

Because debere itself is a verb that normally takes an infinitive.

Start with the direct idea:

• Puella reliquos nummos servare debet.
  = The girl ought to save the remaining coins.

Here:

• debet = ought / must
• servare = to save

When this becomes indirect statement after dicit, the finite verb debet changes to the infinitive debere:

• Puella dicit se reliquos nummos servare debere.

So:

• debere is the infinitive required by indirect statement
• servare is the infinitive complement of debere

In other words, debere still needs servare, just as English ought needs to save.

Because reliquos is an adjective agreeing with nummos.

• nummos = coins, accusative plural masculine
• reliquos = remaining / rest of the, also accusative plural masculine

So:

• reliquos nummos = the remaining coins

They are accusative because they are the object of servare:

• servare reliquos nummos = to save the remaining coins

Yes, nummos literally means coins.

Latin often talks about money in more concrete terms than English does. Where English might say:

• save the rest of her money

Latin may say:

• save the remaining coins

So reliquos nummos is perfectly natural Latin, even if English translation may sound smoother with money in some contexts.

Because Latin often includes the noun subject even when the verb ending already gives enough information.

• cupit already tells us the subject is he/she/it
• puella makes clear that the subject is the girl

Latin can either:

• state the subject explicitly, or
• leave it understood from the verb ending and context

So:

• Puella ... cupit = The girl wants...
• ... cupit by itself could mean she wants or he wants depending on context

Including puella makes the sentence clear and also gives a good starting point for the sentence.

Because Latin has no articles.

Latin does not have separate words for:

• a / an
• the

So puella can mean:

• a girl
• the girl

The context tells you which is more natural in translation.

The same is true elsewhere in the sentence:

• nummos could be coins or the coins
• reliquos nummos is usually best understood as the remaining coins

The basic meaning does not depend mainly on word order, because the endings show the grammar. But the word order does help with emphasis and flow.

A few things to notice:

• Puella comes first, setting the topic
• aliquid dulce stays together because it is one idea: something sweet
• sed ipsa puts emphasis on she herself
• reliquos nummos stays together because adjective and noun belong together

Latin word order is more flexible than English, but it is not random. Writers often arrange words to highlight contrast, emphasis, or rhythm.

Here the order feels natural and slightly expressive:

• first her desire,
• then the contrast introduced by sed,
• then her own statement about what she ought to do.

In some contexts, forms like aliquid can overlap a little with English something or anything, but here something sweet is the natural reading.

That is because the sentence is not a question, negative, or conditional environment where English often prefers anything. It is a straightforward positive statement:

• Puella aliquid dulce emere cupit
  = The girl wants to buy something sweet

So in this sentence, something sweet is the best understanding.

Here aliquid is accusative singular, because it is the object of emere.

• emere = to buy
• what does she want to buy?
  aliquid dulce

The tricky part is that aliquid looks the same in nominative and accusative, because it is neuter singular. So you identify its case mainly from its job in the sentence.

Since it is what is being bought, it must be accusative.

Their dictionary forms are:

• cupit → cupio, cupere = to desire, want
• dicit → dico, dicere = to say
• debere → debeo, debere = to owe; to ought, must

In this sentence:

• cupit = 3rd person singular present active
• dicit = 3rd person singular present active
• debere = present active infinitive

Learning to connect the sentence form to the dictionary form is a big part of reading Latin comfortably.
