Si mater margaritas et gemmas non emerit, artifex tamen fibulam nitidam ei servabit.

Because emerit here is a future perfect indicative, not an ordinary perfect.

In this kind of sentence, Latin often uses:

• si
  • future perfect
• main clause with future

So:

• Si mater ... non emerit = if the mother does not/will not have bought...
• artifex ... servabit = the craftsman will keep...

English usually smooths this out as if the mother does not buy... the craftsman will keep...

Latin uses the future perfect in the if-clause to show that this action must happen first, before the result in the main clause.

The two verbs are in different future tenses because the actions happen at different times relative to each other.

• emerit = future perfect: the buying is viewed as something that will already be completed or not completed first
• servabit = future: the keeping happens afterward

So the sense is:

• If the mother has not bought the pearls and gems,
• then the craftsman will keep a shining brooch for her.

Latin is being precise about sequence.

No. In this sentence, emerit is best taken as future perfect indicative.

That is important, because learners often associate -erit with forms that can look confusing. But here, after si, with a future verb in the main clause (servabit), the natural interpretation is:

• emerit = future perfect indicative
• not a subjunctive form

This is a normal future condition in Latin.

Both are accusative plural because they are the direct objects of emerit (will buy / will have bought).

The verb emo takes a direct object in the accusative:

• margaritas = pearls
• gemmas = gems/jewels

So mater margaritas et gemmas emerit means the mother buys/will have bought pearls and gems.

Because they have different jobs in the sentence.

• mater is the subject of emerit, so it is in the nominative
• ei means to her / for her, so it is in the dative

In the main clause:

• artifex = subject, nominative
• fibulam nitidam = direct object, accusative
• ei = indirect object, dative

So ei servabit means he will keep it for her.

Ei is the dative singular form of the pronoun is, ea, id.

Here it means:

• to her
• or for her

Since the sentence already mentions mater, the pronoun naturally refers back to her.

So:

• artifex ... ei servabit = the craftsman will keep ... for her

Because Latin word order is flexible. Nitidam is an adjective modifying fibulam, and adjectives can come before or after the noun.

What matters most is agreement, not position:

• fibulam = accusative singular feminine
• nitidam = accusative singular feminine

So they clearly go together: fibulam nitidam = a shining/polished/elegant brooch

Latin often uses word order for emphasis or style rather than basic grammar.

Because of the accusative case.

• fibulam is accusative singular
• nitidam agrees with it in accusative singular feminine

The verb servare can take a direct object, so fibulam nitidam is what the craftsman will keep.

Meanwhile:

• artifex is nominative, so it is the subject
• ei is dative, so it is the indirect object

Tamen means nevertheless, still, or all the same.

It signals contrast:

• even if the mother does not buy the pearls and gems,
• still the craftsman will keep a brooch for her

So tamen emphasizes that the action in the main clause happens despite the condition in the if-clause.

Latin adverbs like tamen can often move around more freely than in English.

Here artifex tamen gives a natural emphasis:

• the craftsman, nevertheless, will keep...

It highlights the contrast at the start of the main clause. Latin word order often helps show emphasis, transition, or balance between clauses.

Not always, but in a straightforward future condition like this, yes.

This sentence is a normal, open condition:

• Si mater ... non emerit, artifex ... servabit.
• If the mother does not buy..., the craftsman will keep...

Latin commonly uses the indicative for real or possible conditions like this.

The subjunctive is used in other kinds of conditions, especially more hypothetical or contrary-to-fact ones.

Because non usually negates the word or phrase that follows, and here it negates the verb:

• non emerit = will not buy / will not have bought

That is the most straightforward placement. It clearly tells us that the buying is what is being denied.

Because Latin has no articles.

So:

• mater can mean mother or the mother
• artifex can mean craftsman or the craftsman
• fibulam nitidam can mean a shining brooch or the shining brooch, depending on context

English has to choose an article when translating, but Latin does not mark that distinction directly.

Yes, very often.

For example, Latin could rearrange the words and still keep the same basic meaning because the endings show each word’s role:

• Si mater non margaritas et gemmas emerit, artifex fibulam nitidam ei tamen servabit
• or Artifex tamen ei fibulam nitidam servabit

These would sound different in emphasis or style, but the case endings still tell you:

• who does the action
• what is bought
• what is kept
• for whom it is kept

That flexibility is one of the big differences between Latin and English.
