Aurifex gemmam parvam lente polit, ut clarior fiat.

Aurifex is in the nominative singular, which is the case normally used for the subject of a finite verb.

You can also tell it is the subject because polit is 3rd person singular, so it matches a single doer: aurifex.

A learner may also want to know that aurifex is a 3rd-declension noun. Its genitive is aurificis.

Because both words are in the accusative singular feminine:

• gemmam = the direct object
• parvam = an adjective describing gemmam

In Latin, adjectives must agree with the nouns they describe in:

• gender
• number
• case

So if gemmam is accusative singular feminine, parvam must be too.

Polit is:

• 3rd person singular
• present tense
• active voice
• indicative mood

It comes from polio, polire, meaning to polish.

So polit means he/she polishes or is polishing, depending on context.

Lente is an adverb, not an adjective. It means slowly and modifies the verb polit.

It does not agree with a noun, because adverbs do not show case, number, and gender agreement the way adjectives do.

A useful comparison:

• lentus / lenta / lentum = slow as an adjective
• lente = slowly as an adverb

So here it tells us how the goldsmith polishes the gem.

Here ut introduces a purpose clause.

It means:

• so that
• in order that

So ut clarior fiat explains the purpose of the polishing: the goldsmith polishes the gem slowly so that it may become brighter.

Because ut purpose clauses normally take the subjunctive in Latin.

So after ut meaning so that / in order that, Latin uses a subjunctive verb to express the intended result or purpose, not just a plain statement of fact.

Since the main verb polit is present tense, the purpose clause uses the present subjunctive: fiat.

Fiat is the 3rd person singular present subjunctive of fio, fieri.

In this sentence it means become:

• ut clarior fiat = so that it may become brighter

This is a very common verb in Latin. Depending on context, fio can mean things like:

• become
• happen
• be made

Here become is the best sense.

Because clarior is a predicate adjective in the ut clause, and it goes with the subject of fiat, not with the direct object of polit.

The understood subject of fiat is the gem:

• main clause: aurifex gemmam parvam lente polit
• purpose clause: ut [ea/gemma] clarior fiat

If we filled it out more explicitly, we could say:

• ut ea clarior fiat

Since the implied subject is nominative, the adjective is also nominative: clarior.

It is not accusative, so clariorem would be wrong here.

Because clarior is the comparative form of the adjective.

In the comparative, the nominative singular masculine and feminine have the same form:

• masculine: clarior
• feminine: clarior
• neuter: clarius

So even though the implied subject is feminine (gemma), the correct form is still clarior, not clara.

Yes. That is exactly what is happening.

In the main clause:

• gemmam is the direct object of polit

In the purpose clause:

• the same gem is understood as the subject of fiat

English does this too in sense, even if the grammar looks less obvious:

• He polishes the gem so that it becomes brighter.

Latin often leaves that repeated pronoun unstated because it is easy to understand from context.

Latin word order is much more flexible than English word order because the endings show the grammatical relationships.

This sentence puts the words in a natural Latin arrangement:

• Aurifex = subject
• gemmam parvam = object + its adjective
• lente = adverb
• polit = verb
• ut clarior fiat = purpose clause

Latin often places the verb later than English does, and subordinate clauses often come after the main clause.

So the order may feel unusual to an English speaker, but the endings make the structure clear.

Yes, to a large extent.

Because Latin relies on inflectional endings, many rearrangements are still grammatical. For example, moving lente or aurifex would not necessarily change the basic meaning.

However, word order still affects:

• emphasis
• style
• what is highlighted

So Latin word order is flexible, but it is not random. The writer chooses an order for effect as well as grammar.
