Condicio pacis clara est.

Condicio is nominative singular. It is the subject of the sentence—the thing being talked about.

In Condicio pacis clara est, the sentence is saying something about condicio, so it appears in the nominative case.

Pacis is the genitive singular of pax, meaning of peace.

So Latin is using the genitive to show a relationship:

• pax = peace
• pacis = of peace

That is why pacis modifies condicio: it tells you what kind of condition or the condition of what.

Because clara is describing condicio, and Latin adjectives must agree with the nouns they describe in:

• gender
• number
• case

Since condicio is feminine singular nominative, the adjective must also be feminine singular nominative:

• clara

So:

• clarus would be masculine
• clarum would be neuter
• clara matches condicio

Est means is and is the 3rd person singular present form of esse (to be).

Here it acts as a linking verb. It connects the subject condicio with the adjective clara.

So the structure is basically:

• condicio = subject
• est = is
• clara = clear

In other words, est links the condition of peace with the description clear.

Latin word order is much more flexible than English word order because the endings show the grammar.

Putting the verb at the end is very common in Latin, especially in straightforward prose. So:

• Condicio pacis clara est
• Clara est condicio pacis
• Pacis condicio clara est

can all be grammatical, though they may differ slightly in emphasis.

So the final est is normal Latin style, not something strange.

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

So condicio can mean:

• a condition
• the condition

You decide which is meant from the context.

That is very normal in Latin. Learners often want to supply an article automatically, but Latin usually leaves it unstated.

Both condicio and pax are third-declension nouns.

That is why their forms may not look as predictable as first- or second-declension nouns.

For example:

• condicio → genitive condicionis
• pax → genitive pacis

A learner often notices that pax changes a lot in the genitive, and that is just a normal feature of the third declension.

It is working predicatively, not attributively.

That means clara is not simply sitting next to a noun as in the clear condition. Instead, it is part of the statement made about the subject:

• The condition of peace is clear

So clara is a predicate adjective, linked to condicio by est.

Yes, often they can.

Because Latin uses case endings, the basic relationships stay clear even if the order changes. For example, these are all possible Latin word orders:

• Condicio pacis clara est
• Pacis condicio clara est
• Clara est condicio pacis

The basic meaning stays the same, though the emphasis may shift:

• putting clara earlier can emphasize clear
• putting pacis earlier can emphasize peace

So word order in Latin often affects focus more than basic grammar.

Both spellings are found, but condicio is an old and very good Latin spelling.

In many texts, especially later ones or in dictionaries for beginners, you may see conditio instead. But condicio is not a mistake.

So if you meet:

• condicio
• conditio

you should recognize them as forms of the same word.

A simple parsing would be:

• Condicio — noun, nominative singular feminine, subject
• pacis — noun, genitive singular feminine, dependent on condicio
• clara — adjective, nominative singular feminine, agreeing with condicio
• est — verb, 3rd person singular present active indicative of esse

So the grammatical skeleton is:

subject + genitive modifier + predicate adjective + linking verb
