Servus paratus est.

• servus = slave, servant, or sometimes attendant, depending on context
• paratus = ready, prepared
• est = is

So the sentence is built very literally as The servant/slave ready is.

Servus is nominative singular.

You can tell because:

• it ends in -us, a very common ending for a second-declension masculine nominative singular
• it is the subject of the sentence: the person who is ready

Its dictionary form is also servus, so here the word appears in its basic nominative singular form.

Because paratus agrees with servus.

In Latin, adjectives must match the nouns they describe in:

• gender
• number
• case

Since servus is:

• masculine
• singular
• nominative

the adjective must also be:

• masculine
• singular
• nominative

So Latin uses paratus, not parata or paratum.

It is both historically related to a verb and functioning here as an adjective.

Paratus comes from the verb paro, parare, meaning prepare.
It is originally the perfect passive participle: prepared.

But in this sentence it works like an ordinary adjective meaning:

• ready
• prepared

So Servus paratus est can be understood as The servant is ready or more literally The servant is prepared.

Est is the third person singular present indicative active of sum, esse, meaning to be.

So:

• sum = I am
• es = you are
• est = he/she/it is

Because servus is singular, Latin uses est, not sunt.

Latin normally has no articles.

So servus can mean:

• a servant
• the servant
• sometimes simply servant

You figure out which one sounds best from the context.

That is very different from English, where we usually need an article.

Latin often leaves subject pronouns unstated because the verb ending already shows the person and number.

Here est already means he/she/it is.

So Latin does not need to say he explicitly.
If Latin wanted extra emphasis, it could add a pronoun such as is, but normally that is unnecessary.

No, Latin word order is fairly flexible.

Because the endings show the grammar, the same basic idea could appear in different orders, such as:

• Servus paratus est
• Paratus est servus
• Servus est paratus

These can all mean the same thing, though the emphasis may shift slightly.

In simple textbook sentences, placing est at the end is very common.

It very often means slave in classical Latin, though in some contexts servant is a smoother English translation.

A native English speaker should know that servus is not always a mild household helper. In many Roman contexts, it refers to an enslaved person.

So the best English meaning depends on context, tone, and the translation style being used.

Sometimes Latin can omit a form of to be, especially in poetry, informal style, headings, or very compressed expressions.

But in normal straightforward prose, Servus paratus est is the standard full sentence.

So for a learner, it is best to understand est as an important part of the sentence.

A simple classroom pronunciation would be something like:

SER-woos pah-RAH-tus est

More carefully:

• servus = SER-woos
• paratus = pah-RAH-toos
• est = est

A few helpful points:

• v is pronounced like w in classical pronunciation
• u is pronounced like oo
• stress in paratus falls on the second syllable: pa-RA-tus

A learner would normally want these:

• servus, servi m. = servant, slave
• paratus, -a, -um = ready, prepared
  or, if learning the related verb: paro, parare, paravi, paratus = prepare
• sum, esse, fui = be

This is useful because Latin words in sentences often appear in forms different from the way they are listed in a dictionary.
