Il cartello indica chiaramente l'uscita.

• Il = the (masculine singular definite article)
• cartello = sign
• indica = indicates / points out / shows
• chiaramente = clearly
• l'uscita = the exit

So the structure is:

Il cartello = the subject
indica = the verb
chiaramente = the adverb
l'uscita = the direct object

Because uscita begins with a vowel, the feminine singular article la is usually shortened to l' before it.

So:

• la porta = the door
• la macchina = the car
• l'uscita = the exit
• l'acqua = the water

This is called elision. In writing, you must include the apostrophe: l'uscita.

Italian masculine singular definite articles change depending on the sound that follows.

Use il before most consonants:

• il cartello
• il libro
• il tavolo

Use lo before words beginning with:

• z: lo zaino
• s + consonant: lo studente
• ps: lo psicologo
• gn: lo gnomo
• x: lo xilofono

Since cartello starts with a simple c, the correct article is il.

Indica is the third person singular present tense of the verb indicare.

The infinitive is indicare = to indicate / to point out / to show.

Present tense:

• io indico = I indicate
• tu indichi = you indicate
• lui/lei indica = he/she indicates
• noi indichiamo = we indicate
• voi indicate = you all indicate
• loro indicano = they indicate

So Il cartello indica... means The sign indicates...

Because Italian normally does not use subject pronouns unless they are needed for emphasis or clarity.

English must say:

• It indicates the exit

Italian usually just says:

• Indica l'uscita

But here the subject is explicitly a noun:

• Il cartello indica l'uscita

You do not need to add esso. In fact, using esso in everyday Italian often sounds unnatural or overly formal.

Because uscita is the direct object of indicare.

In English, some verbs need a preposition and some do not. Italian works the same way.
Indicare takes a direct object:

• indicare la strada = to indicate the road
• indicare il problema = to indicate the problem
• indicare l'uscita = to indicate the exit

So l'uscita comes directly after the verb, with no a, di, or other preposition.

Yes, adverbs like chiaramente can sometimes move, but the version here is very natural:

• Il cartello indica chiaramente l'uscita.

This places chiaramente near the verb, which is common.

You may also hear:

• Il cartello chiaramente indica l'uscita.
• Chiaramente, il cartello indica l'uscita.

But these can sound more marked, literary, or like they emphasize clearly in a different way.

For a learner, the safest pattern is: subject + verb + adverb + object

Usually, yes. It comes from the adjective chiaro = clear.

• chiaro = clear
• chiaramente = clearly

Like many Italian adverbs, it is formed with -mente, similar to English -ly:

• rapido → rapidamente = quickly
• facile → facilmente = easily
• chiaro → chiaramente = clearly

Depending on context, chiaramente can also mean something like obviously or plainly, but clearly is the basic meaning.

Because nouns in Italian have grammatical gender, and uscita is simply a feminine noun.

You can tell here because it takes the feminine article:

• l'uscita

Many nouns ending in -a are feminine, and uscita follows that pattern.

It comes from the verb uscire = to go out / to exit.
As a noun, uscita means exit, way out, or sometimes outing / release, depending on context.

In this sentence, it means exit.

A simple approximate pronunciation is:

• l'uscita: loo-SHEE-ta
• chiaramente: kya-ra-MEN-te

A few helpful points:

• uscita has the stress on -sci-: u-SCI-ta
• In uscita, sc before i sounds like sh
• In chiaramente, chi sounds like kee/kya with a hard k sound, not like English ch

So:

• chiaramente does not begin with an English ch sound
• uscita does contain a sh sound

Sometimes, but not always.

Indicare often means:

• to indicate
• to show
• to point out

In some contexts, English might naturally say point to, but Italian indicare does not always imply a physical pointing gesture.

So in this sentence:

• Il cartello indica chiaramente l'uscita

the most natural translation is usually:

• The sign clearly indicates the exit or
• The sign clearly shows the exit

If you specifically mean physically pointing with a finger, Italian often uses indicare con il dito or similar wording.

Yes, that is grammatically correct, but the meaning shifts slightly.

• indicare = indicate, point out
• mostrare = show

Both can work, but indicare is especially natural for signs, directions, labels, and symbols.

So for a sign, indica often sounds more idiomatic:

• Il cartello indica l'uscita.

Mostra is also possible, but it may sound a bit more like the sign is visually displaying it rather than marking or indicating it.

You would change the article, noun, verb, and object article/noun as needed:

• Il cartello indica chiaramente l'uscita.
• I cartelli indicano chiaramente le uscite.

Changes:

• Il → I
• cartello → cartelli
• indica → indicano
• l'uscita → le uscite

So the plural means: The signs clearly indicate the exits.
