Puella tamen hoc ornamentum sumere vult, quia diem festum cras celebrabit.

Tamen means however, nevertheless, or still. In Latin, words like tamen often appear near the beginning of the sentence, sometimes in the second position. So Puella tamen... is very natural Latin.

English usually puts however first or separates it with punctuation, but Latin word order is more flexible. Here, tamen is highlighting a contrast: the girl, however, wants...

Puella is nominative singular, from the first-declension noun puella, puellae meaning girl.

We know it is the subject because:

• the nominative case is normally used for the subject in Latin
• the verb vult is third person singular, so it matches puella
• the sentence is about what the girl wants and will do

So puella is the one doing the actions.

Hoc ornamentum means this ornament.

Both words are accusative singular neuter:

• hoc = accusative singular neuter of hic, haec, hoc
• ornamentum = accusative singular neuter of ornamentum, ornamenti

They are in the accusative because they are the direct object of sumere. In other words, this is the thing the girl wants to take or put on.

Since ornamentum is neuter singular, the demonstrative has to agree with it, so Latin uses hoc, not hunc or hanc.

Sumere is the present active infinitive of sumo, meaning to take, to put on, or sometimes to wear, depending on context.

It is in the infinitive because it depends on vult:

• vult = she wants
• sumere = to take / to put on

So sumere vult means she wants to take or she wants to put on.

This is a very common Latin construction: a finite verb of wanting, being able, beginning, etc. plus an infinitive.

Not literally in every context, but it can be used that way with clothing, adornment, or similar items. Its basic meaning is to take up or to take, but in context it can mean:

• to put on
• to assume
• to wear

With ornamentum, the idea is probably that the girl wants to put on or wear this ornament.

So Latin uses a broader verb where English might choose a more specific one.

Quia means because, and it introduces a subordinate clause with a normal finite verb.

So:

• quia = because
• diem festum cras celebrabit = she will celebrate a festival day tomorrow

Latin does not use an infinitive here because this is not an indirect statement. It is a regular because-clause, so a normal verb form is exactly what we expect.

Because diem festum is the direct object of celebrabit.

• dies festus = nominative, a festival day as subject
• diem festum = accusative, a festival day as object

Since she will celebrate the festival day, Latin puts it in the accusative.

Both words agree:

• diem = accusative singular masculine
• festum = accusative singular masculine adjective

Celebrabit is future indicative active, third person singular, from celebro, celebrare.

It means she will celebrate.

It is formed from the present stem celebra- plus the future marker for first-conjugation verbs:

• celebrabo = I will celebrate
• celebrabis = you will celebrate
• celebrabit = she/he/it will celebrate

The future tense fits well with cras, which means tomorrow.

Cras is an adverb meaning tomorrow.

It tells us when she will celebrate. Since it is an adverb, it does not change form. It is not in a case like a noun.

Latin often places time adverbs flexibly, so cras could appear in different positions without changing the basic meaning. Here it stands close to celebrabit, which makes good sense: she will celebrate tomorrow.

Latin often leaves subject pronouns unstated because the verb ending already shows the person and number.

• vult = she/he/it wants
• celebrabit = she/he/it will celebrate

Since puella is already present as the subject, Latin does not need an extra word for she. Adding ea would usually be unnecessary unless you wanted special emphasis.

Not very literal. Latin word order is much freer than English word order because the endings show how words function.

A learner should focus first on the grammar:

• puella = subject
• hoc ornamentum = object of sumere
• sumere vult = wants to take/put on
• quia = introduces the reason
• diem festum = object of celebrabit
• cras celebrabit = will celebrate tomorrow

Once you identify the structure, you can translate into more natural English rather than keeping the Latin order exactly.
