Mimus et pantomimus in pulpito sunt.

Because mimus et pantomimus means the mime and the pantomime actor: two people joined by et (and).

In Latin, just as in English, two singular nouns connected by and usually make a plural subject, so the verb must be plural too:

• mimus est = the mime is
• pantomimus est = the pantomime actor is
• mimus et pantomimus sunt = the mime and the pantomime actor are

So sunt is the correct plural form of esse (to be).

They are both nominative singular.

That is because they are the subject of the sentence:

• mimus = nominative singular
• pantomimus = nominative singular

Even though there are two nouns, each one is individually singular. Together they form a compound subject, which is why the verb is plural.

Because in can take different cases depending on the meaning.

Here it expresses location: in/on the stage, meaning where someone is. For that meaning, Latin uses in + ablative.

So:

• pulpitum = nominative or accusative singular
• pulpito = ablative singular

Therefore:

• in pulpito = on/in the stage or more naturally on the stage

A helpful rule is:

• in + ablative = in/on somewhere, indicating position
• in + accusative = into/onto somewhere, indicating motion toward

It is the ablative singular of pulpitum.

So the forms are:

• pulpitum = nominative singular / accusative singular
• pulpiti = genitive singular
• pulpito = dative or ablative singular

In this sentence, pulpito is specifically ablative singular because it follows in in the sense of location.

Because Latin normally does not use articles like English the or a/an.

So:

• mimus can mean a mime or the mime
• pantomimus can mean a pantomime actor or the pantomime actor
• in pulpito can mean on a stage or on the stage

Which English article you choose depends on context. Latin leaves that unstated unless something else in the sentence makes it clear.

In natural English, on the stage is better.

Latin in covers a wider range than English in does. Depending on the noun and context, in + ablative can be translated as:

• in
• on
• sometimes at

With pulpitum (stage/platform), English idiom normally prefers on the stage, even though the Latin uses in.

Yes, Latin word order is much more flexible than English word order.

This sentence is perfectly normal, but other orders are also possible, such as:

• In pulpito mimus et pantomimus sunt
• Mimus et pantomimus sunt in pulpito

The basic meaning stays the same because the endings tell you the grammar.

The given order is fairly straightforward:

• subject: mimus et pantomimus
• place phrase: in pulpito
• verb: sunt

Latin often puts the verb near the end, but it does not have to.

Sunt is the third person plural present indicative active of esse (to be).

Its basic present forms are:

• sum = I am
• es = you are
• est = he/she/it is
• sumus = we are
• estis = you all are
• sunt = they are

Since the subject is mimus et pantomimus (two people), Latin uses sunt = are.

Yes. In this sentence, both are treated as masculine second-declension nouns.

That is why they have the nominative singular ending -us:

• mimus
• pantomimus

A learner may notice that they look Greek, and that is because they are Greek loanwords in Latin. But for this sentence, the important point is that they behave like ordinary masculine nouns in -us.

Usually, yes. When et joins two nouns, the result is normally a plural subject.

So:

• mimus et pantomimus → two people
• therefore sunt, not est

This works the same way with many other nouns:

• puella et poeta sunt = the girl and the poet are

So one very useful habit is: if you see X et Y as the subject, expect a plural verb.

A careful classroom pronunciation would be something like:

MEE-mus et pan-TOH-mee-mus in POOL-pi-toh soont

If you want a more classical-style guide:

• mimus = MEE-moos
• et = et
• pantomimus = pan-toh-MEE-moos
• in = in
• pulpito = POOL-pi-toh
• sunt = soont

If your course uses macrons, you may see:

Mīmus et pantomīmus in pulpito sunt.

Those macrons mainly help show vowel length in pronunciation and meter; they do not change the basic grammar of the sentence.
