Emptor placidus pretium iterum rogat, nec clamat.

Emptor means buyer.

It is:

• nominative singular
• a masculine noun
• the subject of both verbs: rogat and clamat

So emptor placidus together means the calm buyer.

Placidus is an adjective meaning calm, quiet, or gentle.

It is in the same form as emptor because it describes it:

• nominative
• singular
• masculine

This is normal Latin agreement: adjectives match the nouns they describe in gender, number, and case.

Classical Latin has no definite article and no indefinite article.

So:

• emptor can mean buyer, a buyer, or the buyer
• the context or translation tells you which is most natural in English

That is why emptor placidus can be translated as the calm buyer even though there is no separate word for the.

Pretium is accusative singular.

Here it is the direct object of rogat:

• rogat = asks, asks for, or inquires about
• the thing being asked about is pretium = the price

So the sentence means that the buyer asks the price again.

Pretium is a neuter noun meaning price.

One clue is the ending -um, which is very common for:

• neuter nominative singular
• neuter accusative singular

In this sentence, pretium is accusative because it is the object of rogat.

Since many neuter nouns have the same form in the nominative and accusative singular, you often identify the case from the sentence structure rather than the ending alone.

Rogat is from rogare, meaning to ask.

It is:

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

So rogat means he asks or the buyer asks.

In this sentence, Latin uses rogare with a direct object:

• pretium rogat = he asks the price

A very natural English translation might be:

• he asks the price again
• he asks again about the price
• he asks the price once more

Iterum means again or a second time.

It modifies the verb rogat:

• pretium iterum rogat = asks the price again

Latin adverbs like iterum are often flexible in word order. Its position here is perfectly normal.

Non usually just means not.

Nec means and not or nor.

So:

• clamat = he shouts
• nec clamat = and he does not shout / nor does he shout

Here nec connects the second verb to the first in a smooth, compact way:

• The calm buyer asks the price again, and does not shout.

Because it has the same subject as rogat: emptor.

Latin often states the subject once and then uses multiple verbs with it:

• Emptor ... rogat, nec clamat
• The buyer asks ... and does not shout

So both:

• rogat = he asks
• clamat = he shouts

refer to the same person, the buyer.

It has:

• subject: emptor placidus
• object: pretium
• adverb: iterum
• verb: rogat
• second coordinated verb: nec clamat

A rough structural breakdown is:

Emptor placidus | pretium | iterum | rogat, | nec clamat
The calm buyer | the price | again | asks, | and does not shout

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

Latin relies much more on inflection than English does.

Because forms like emptor and pretium show their roles, Latin can arrange words for:

• style
• emphasis
• rhythm
• clarity

English depends more on word order, so we usually say:

• The calm buyer asks the price again and does not shout.

Latin does not need to keep the words in exactly that order.

Yes. Depending on context, placidus can mean:

• calm
• quiet
• gentle
• peaceful
• composed

So emptor placidus might be translated as:

• the calm buyer
• the quiet buyer
• the composed customer

If the meaning has already been given to the learner, the main thing to notice is that the adjective describes the buyer’s manner and contrasts nicely with nec clamat.

Yes. The sentence reinforces the buyer’s calm character in two ways:

• placidus directly says he is calm
• nec clamat shows that calmness in action: he does not shout

So the second part does more than add information; it confirms the first description. This kind of pairing is very natural in Latin and in English.
