Orbis olearius in torculario manet.

The subject is orbis olearius.

You can tell because:

• orbis is in the nominative singular
• olearius agrees with it in gender, number, and case
• manet is third-person singular, so it matches a singular subject

So the basic structure is:

orbis olearius + in torculario + manet
subject + prepositional phrase + verb

Orbis is a third-declension noun.

Its dictionary form is orbis, orbis, masculine.

That can be surprising to English speakers because:

• many second-declension masculine nouns end in -us
• but orbis ends in -is, which here belongs to the third declension

In this sentence, orbis is nominative singular.

Because it agrees with orbis.

Here, olearius is:

• masculine
• singular
• nominative

That makes it fit naturally as an adjective modifying orbis.

So orbis olearius is one noun phrase: the oil-/olive-related wheel.

It is true that olearius can sometimes be a noun in other contexts, but in this sentence its matching form shows that it is describing orbis.

No, it does not fundamentally change the meaning.

Latin adjective placement is much freer than English adjective placement. An adjective can come:

• before the noun
• after the noun
• sometimes separated from it

So orbis olearius and olearius orbis would describe the same thing, though the style or emphasis might differ.

For a learner, the important thing is not the word order but the agreement of endings.

Because in takes the ablative when it means in, on, or inside a place where something already is.

Here the idea is location, not movement.

So:

• in torculario = in the press-room / in the press
• in + ablative = location

If the sentence meant motion into the place, Latin would normally use in + accusative instead.

Torculario is the ablative singular of torcularium.

Torcularium is a second-declension neuter noun.

So its singular forms include:

• nominative: torcularium
• accusative: torcularium
• ablative: torculario

Because it follows in in a location phrase, the ablative torculario is exactly what we expect.

Manet is:

• present tense
• active voice
• indicative mood
• third person singular

It comes from the verb maneo, manere, meaning remain, stay, or continue to be.

So grammatically, manet means he/she/it remains or stays.

Since the subject is a thing, in English we naturally understand it as it remains or it stays.

Because that is a very common Latin word order.

Latin often places the verb last, especially in simple statements. So:

Orbis olearius in torculario manet.

is a very natural Latin arrangement.

But Latin word order is flexible because the endings show the grammar. The sentence could be rearranged in other ways and still mean basically the same thing.

Because classical Latin has no articles.

So a noun like orbis can mean:

• a wheel
• the wheel

and torculario can mean:

• in a press-room
• in the press-room

The context tells you which English article makes the most sense.

This is very normal in Latin and something English speakers have to get used to.

Because the preposition in marks the whole phrase as a prepositional phrase, not as the subject.

A Latin subject is normally in the nominative case and not introduced by a preposition. Here:

• orbis olearius = nominative subject
• in torculario = prepositional phrase showing place
• manet = verb

So in torculario tells you where the subject remains.

It can mean either, depending on context.

The word is connected with a press, especially for things like wine or oil. In different contexts it may refer to:

• the press
• the pressing apparatus
• the press-room

So if you have already been given one specific meaning in your text, use that meaning there. Just remember that the Latin word itself can have a slightly broader range.

A very useful habit is to identify each part by its form:

• orbis = nominative singular noun
• olearius = nominative singular masculine adjective agreeing with orbis
• in = preposition
• torculario = ablative singular after in
• manet = third-person singular present verb

So instead of reading only by word order, you read by endings and agreement. That is one of the most important skills in Latin.
