Nonne cera a cerario venditur?

Nonne introduces a question that expects the answer yes.

So Nonne cera a cerario venditur? is not just a neutral question like Is wax sold by the wax-seller? It has the sense of:

• Isn’t wax sold by the wax-seller?
• Surely wax is sold by the wax-seller, isn’t it?

A learner should notice that nonne often signals the speaker’s expectation that the statement is true.

Venditur means is sold. It is the 3rd person singular present passive of vendo, vendere (to sell).

The ending -tur is the key sign here: it marks a passive verb in the present tense.

So:

• vendit = he/she/it sells
• venditur = he/she/it is sold

Because the sentence is passive, cera becomes the grammatical subject: wax is sold.

In a passive sentence, the thing receiving the action becomes the subject.

Here, cera is the thing being sold, so in English it may feel like the “object” of the idea, but in Latin grammar it is actually the subject of the passive verb venditur.

That is why cera is in the nominative singular:

• cera = wax as the subject
• venditur = is sold

So the structure is literally:

• wax
  • by the wax-seller
    • is sold

In a passive sentence, the personal agent — the person who performs the action — is usually expressed with a or ab plus the ablative.

So:

• a cerario = by the wax-seller

This is the normal way to show who is doing the action in a passive construction.

Compare:

• Puella amatur a poeta = The girl is loved by the poet
• Cera a cerario venditur = Wax is sold by the wax-seller

Without a/ab, cerario would not clearly express the personal agent in standard Latin prose.

Cerario is ablative singular.

It is ablative because it follows a, which here introduces the personal agent in a passive sentence.

The dictionary form is cerarius. Its singular forms would be:

• nominative: cerarius
• genitive: cerarii
• dative: cerario
• accusative: cerarium
• ablative: cerario

So a cerario means by the wax-seller.

Both a and ab mean the same thing here: by.

In classical Latin:

• ab is more common before vowels and sometimes before consonants too
• a is commonly used before consonants

Since cerario begins with c, a cerario is perfectly normal.

So this is just a regular stylistic/phonetic choice, not a change in meaning.

Cerarius is a noun meaning a person connected with wax (cera). In this sentence it is usually understood as something like:

• wax-seller
• wax-dealer
• wax merchant

The word is built from cera (wax) plus the ending -arius, which often forms occupational words in Latin.

A learner can often spot this pattern:

• base noun + -arius = person associated with that thing

So cerarius is literally a wax-person, that is, someone whose trade involves wax.

Latin word order is much freer than English word order because the grammatical endings show what each word is doing.

This sentence could be arranged in different ways without changing the basic meaning, for example:

• Nonne cera a cerario venditur?
• Nonne a cerario cera venditur?
• Cera nonne a cerario venditur?

The chosen order puts cera early and the verb venditur at the end, which is very common in Latin.

A good rule for learners is: do not rely only on word order; pay close attention to endings and constructions.

Yes. Although a/ab can often mean from, in this sentence it means by, because it is attached to a passive verb and names the agent.

So the grammar tells you how to understand it:

• with movement or separation, a/ab often means from
• with a passive verb, a/ab + ablative often means by

Since venditur is passive, a cerario is naturally understood as the doer of the action: by the wax-seller.

Yes. The active version would be something like:

• Cerarius ceram vendit = The wax-seller sells wax

Compare the two:

• Cerarius ceram vendit = active
• Cera a cerario venditur = passive

In the active sentence:

• cerarius is the subject
• ceram is the direct object

In the passive sentence:

• cera becomes the subject
• a cerario expresses the agent

Seeing both versions side by side is a very useful way to understand Latin voice.

The subject cera is singular, and the verb agrees with it.

So:

• cera = singular
• venditur = is sold (singular)

If the subject were plural, the verb would also be plural:

• cerae a cerario venduntur = waxes or wax items are sold by the wax-seller

The ending -tur is singular passive, while -ntur is plural passive.

No. Latin has several ways to ask yes/no questions.

For example:

• plain question by tone or context
• -ne attached to the first word for a neutral question
• nonne for a question expecting yes
• num for a question expecting no

So the choice of nonne is important. It tells you this is not just any question, but one with an expected affirmative answer.
