Pavimentum inaequale est.

Pavimentum is a noun. It is a neuter noun of the second declension.

Its dictionary form is:

• pavimentum, pavimentī = floor, pavement, surface

In this sentence it is in the nominative singular, because it is the subject of est.

Because inaequale is an adjective agreeing with pavimentum.

Since pavimentum is:

• neuter
• singular
• nominative

the adjective must also be:

• neuter
• singular
• nominative

The adjective comes from the dictionary form:

• inaequālis, inaequāle = uneven, unequal

This is a third-declension adjective, and its neuter nominative singular ends in -e.

Latin normally has no articles. That means there is no separate word exactly like English the or a/an.

So pavimentum can mean:

• a floor
• the floor
• sometimes just floor, depending on context

The context tells you which English translation sounds most natural.

Est is the third person singular present tense of esse, which means to be.

So est means:

• is

Because the subject pavimentum is singular, Latin uses singular est, not plural sunt.

Yes. This is a very normal Latin pattern:

• subject + adjective + est

The adjective inaequale is a predicate adjective. It does not describe the noun inside a noun phrase like the uneven floor; instead, it says something about the subject:

• The floor is uneven

So Latin is using the same basic idea as English is uneven.

Yes. Latin word order is much freer than English word order because the endings show the grammar.

So these could all mean the same thing:

• Pavimentum inaequale est
• Pavimentum est inaequale
• Inaequale pavimentum est
• Inaequale est pavimentum

However, the choice of order can change the emphasis or style. The given order is straightforward and natural.

You know from the case ending and from the verb.

• pavimentum here is nominative singular
• the nominative case is commonly used for the subject

Also, est is a form of to be, which usually links the subject to a description rather than taking a direct object.

So the structure is:

• pavimentum = subject
• inaequale = description of the subject
• est = linking verb

Because after a linking verb like est, Latin often puts both the subject and its predicate adjective in the nominative.

This is similar to English:

• The floor is uneven

Here, uneven is not an object; it is a description of the subject. Latin marks that by using the nominative for the predicate adjective as well.

A good set of dictionary forms would be:

• pavimentum, pavimentī = floor, pavement
• inaequālis, inaequāle = uneven, unequal
• sum, esse, fuī, futūrus = to be

For a beginner, it is especially useful to remember that:

• pavimentum is second declension neuter
• inaequālis, inaequāle is a third-declension adjective
• est comes from esse

A common classroom pronunciation would be roughly:

• in-eye-KWAA-leh in restored/classical style

More carefully, syllable by syllable:

• in-ae-qua-le

A few helpful points:

• ae is usually pronounced like ai in aisle in restored pronunciation
• qu is pronounced like kw
• the stress falls on quā: inaequāle

If your class uses an ecclesiastical pronunciation, it may sound a bit different, but the spelling and grammar stay the same.

In Latin, adjectives can come before or after the nouns they go with. Both are possible.

So both of these are possible in principle:

• pavimentum inaequale
• inaequale pavimentum

In this sentence, the adjective comes after the noun, which is very common. Latin does not follow English adjective placement rules as strictly as English does.

Yes. It is related to the idea behind English words like:

• inequal
• unequal
• equable
• equation and equal ultimately come from related Latin roots

The adjective is built from:

• in- = not
• a root related to aequus = level, equal, even

So inaequale literally suggests something like not level or not even, which matches its meaning well.
