Histrio cothurnum et soccum ostendit.

Because histrio is in the nominative singular, the case normally used for the subject of a sentence, and ostendit is third person singular, so the verb matches a single subject.

A learner often confirms this by looking at the dictionary form:

• histrio, histrionis = actor, performer

So in this sentence, histrio is the actor/performer who is doing the showing.

Because not all masculine nouns belong to the same declension.

Histrio is a third-declension noun, not a second-declension noun like servus or amicus. In Latin, gender and declension are different things:

• masculine tells you the noun’s gender
• third declension tells you how it changes its endings

So a masculine noun can end in many different ways. Histrio is perfectly normal Latin even though it does not end in -us.

Because they are direct objects, and in this sentence they are in the accusative singular.

Their basic forms are:

• cothurnus
• soccus

These are second-declension masculine nouns. In the accusative singular, -us changes to -um:

• cothurnus → cothurnum
• soccus → soccum

They are the things being shown, so they take the accusative case.

It is two objects joined together by et.

So the sentence has a compound direct object:

• cothurnum
• et
• soccum

In English, this works like boot and slipper/shoe.

Even though there are two objects, the verb stays singular because the subject is singular: only one histrio is doing the action.

Et simply means and.

It connects cothurnum and soccum. It does not change their case; both nouns are accusative because both are direct objects of ostendit.

Because Classical Latin does not have articles like English the or a/an.

So a noun like histrio can mean, depending on context:

• the actor
• an actor
• sometimes just actor

The same is true for cothurnum and soccum. English has to choose an article, but Latin usually leaves that to context.

Ostendit is from the verb ostendere, meaning to show.

In this sentence it is understood as:

• third person singular
• active
• indicative

So it means he/she shows or is showing, depending on how the sentence is being translated.

One useful thing to know: the written form ostendit can also sometimes be a perfect form, meaning showed or has shown. In ordinary Latin spelling, the form can look the same, so context tells you which meaning is intended. Since the meaning has already been given to you here, that tells you how to take it.

Because Latin word order is much more flexible than English word order.

A very common Latin pattern is:

• subject + object + verb

So Histrio cothurnum et soccum ostendit is a very natural Latin order.

Putting the verb at the end often makes the sentence feel neat and complete, but Latin does not have to do this every time.

Yes, often they could.

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

• Histrio ostendit cothurnum et soccum
• Cothurnum et soccum histrio ostendit
• Soccum et cothurnum histrio ostendit

The endings tell you what each word is doing:

• histrio = subject
• cothurnum, soccum = objects

So Latin does not rely on word order as heavily as English does. However, different word orders can give different emphasis.

These are not just any two kinds of footwear; they have a cultural meaning.

• A cothurnus is a high boot, especially associated with tragic actors
• A soccus is a lighter shoe or slipper, especially associated with comic actors

Because of that, the pair can suggest the world of the theater, and even the contrast between tragedy and comedy.

A rough Classical pronunciation would be:

HIS-tri-o ko-THUR-num et SOK-kum os-TEN-dit

A few helpful points:

• c is always hard, like k
• cc in soccum is a doubled consonant
• et is pronounced like et, not like the English letter A
• histrio has four syllables: his-tri-o
• ostendit has three syllables: os-ten-dit

You do not need perfect pronunciation to understand the grammar, but it helps you get used to seeing Latin as a spoken language too.
