Publicanus decumam a possessore exigit.

The subject is publicanus, because it is in the nominative singular form. In Latin, the subject is usually marked by its case ending, not mainly by word order.

Here:

• publicanus = nominative singular, so it is the doer
• decumam = accusative singular, so it is the direct object
• a possessore = ablative phrase, meaning from the possessor/landowner
• exigit = he demands/collects

So publicanus is the person doing the demanding.

Because decumam is the direct object of exigit.

The verb exigere often means to demand, collect, exact, and the thing being demanded is put in the accusative case. So:

• decuma = a tenth, a tithe
• decumam = accusative singular, the tithe as the thing being collected

A native English speaker may expect meaning to depend mostly on word order, but in Latin the ending -am tells you this noun is receiving the action.

Because the sentence means from the possessor/landowner, and Latin normally uses a/ab + ablative to express from with a person.

So:

• possessor = nominative singular
• possessore = ablative singular
• a possessore = from the possessor

If you used possessorem, that would be accusative, which would not fit this construction.

Possessore is ablative singular.

It comes from possessor, possessoris and belongs to the 3rd declension. The ablative singular ending here is -e.

It is ablative because it follows the preposition a, which takes the ablative.

Both a and ab mean from before the ablative. In practice:

• ab is regularly used before vowels and often elsewhere too
• a is commonly used before consonants

Since possessore begins with p, a possessore is perfectly normal.

So this is not a different meaning, just a normal variation in form.

Exigit is the 3rd person singular present active indicative of exigere.

In this sentence it means something like:

• demands
• collects
• exacts

Because the subject is singular (publicanus), the verb is singular too: he demands/collects.

A useful breakdown is:

• exig- = verb stem
• -it = he/she/it in the present tense for this conjugation pattern

Latin word order is much more flexible than English word order because case endings show each word’s job in the sentence.

A very common neutral Latin pattern is:

• subject ... object ... verb

So Publicanus decumam a possessore exigit is a very natural Latin order.

English relies much more on position:

• The tax collector demands the tithe from the possessor

Latin can move words around for emphasis, style, or rhythm, while the endings still keep the meaning clear.

Yes, often they could.

For example, these would still basically mean the same thing:

• Decumam publicanus a possessore exigit
• A possessore publicanus decumam exigit
• Publicanus a possessore decumam exigit

The differences would mostly be about emphasis, not basic grammar.

Because of the case endings:

• publicanus still looks like the subject
• decumam still looks like the object
• possessore still stays ablative after a

It does not simply mean a modern government official.

A publicanus was usually a tax farmer or public contractor in Rome: someone involved in collecting taxes or revenues on behalf of the state, often through a leasing system.

So when a learner sees publicanus, it is better to think:

• tax collector
• or more precisely tax farmer

That helps the sentence make historical sense.

Decuma literally refers to a tenth part, and in many contexts it means a tithe or tax amounting to a tenth, especially on agricultural produce.

So in this sentence, decumam is not just any object; it is a specific type of payment or levy.

That is why the sentence fits a tax-collection context:

• publicanus = tax collector/tax farmer
• decumam = the tithe
• a possessore = from the landholder/owner

Latin has no articles like English the or a/an.

So:

• publicanus can mean a tax collector or the tax collector
• decumam can mean a tithe or the tithe
• possessore can mean a possessor/landowner or the possessor/landowner

You decide from context which English article is best.

This is very common for English speakers to notice, because English usually requires an article, while Latin usually does not.

Their endings show that.

• publicanus is nominative singular
• possessore is ablative singular
• decumam is accusative singular
• exigit is a singular verb form: he/she/it demands

If the sentence were plural, the noun and verb forms would look different. So the grammar is consistent all the way through: one collector, one tithe, one possessor.

Grammatically, possessor means possessor or owner. In context, especially with taxes and tithes, English may translate it more naturally as:

• owner
• landowner
• holder of the property

A learner should remember that Latin words often have a core meaning, while the best English wording depends on context. So a possessore literally means from the possessor, but a smoother translation may use from the landowner.
