La planimetria mostra due vie di fuga.

La is the feminine singular definite article, meaning the.

So:

• la planimetria = the floor plan / the layout plan

In Italian, articles are used more often than in English. A full sentence like this normally sounds more natural with the article.

Yes, planimetria is feminine singular.

You can tell from:

• the article: la
• the ending: many nouns ending in -a are feminine

So the pattern is:

• la planimetria = singular
• le planimetrie = plural

Mostra is the third person singular form of mostrare in the present tense.

The subject is la planimetria, which is singular, so the verb must also be singular:

• la planimetria mostra = the floor plan shows

Compare:

• la planimetria mostra = singular subject
• le planimetrie mostrano = plural subject
• mostrare = infinitive, meaning to show

It is the present indicative.

Here it means something like:

• shows
• is showing (depending on context, though simple present is the basic idea)

In signs, instructions, or technical descriptions, Italian often uses the present tense just like English does.

The noun is via in the singular and vie in the plural.

So:

• una via = one route / way / road
• due vie = two routes / ways

This is an irregular-looking but very common plural pattern for nouns ending in -ia:

• via → vie
• planimetria → planimetrie

After due, the noun must be plural, so vie is required.

Literally, it means something like route of escape.

Breakdown:

• via = way, route
• di = of
• fuga = escape

So vie di fuga means escape routes.

This is a very common Italian structure:

• noun + di
  • noun

Examples:

• sala d’attesa = waiting room
• bicchiere di vino = glass of wine
• via di fuga = escape route

Because Italian often uses di + noun to express type, function, or purpose.

Here, via di fuga means a route for escape or used in escaping, not the route of the escape.

So:

• via di fuga = escape route
• la via della fuga would sound more like the route of the escape / the escape’s route, which is a different idea

In fixed expressions like this, di without an article is normal.

Because fuga is part of the expression via di fuga, where the second noun describes the type or purpose of the first noun.

This is similar to how English often uses one noun to modify another:

• escape route
• train station
• coffee cup

Italian often does this with di:

• via di fuga
• camera da letto
• bicchiere di plastica

So fuga does not need an article here.

Yes. Via is a very flexible word.

It can mean:

• street: abito in via Roma
• way / route: via di fuga
• sometimes even method or means, depending on context

In this sentence, because of di fuga, it clearly means route or way out, not street.

The order is very straightforward:

• La planimetria = subject
• mostra = verb
• due vie di fuga = object

So it follows the common pattern:

subject + verb + object

This matches English quite closely:

• The floor plan shows two escape routes.

Yes, that would be possible.

Both verbs can work in many contexts:

• mostra = shows
• indica = indicates

Mostra feels a bit more direct and visual: the plan visibly shows them.
Indica can sound slightly more formal or technical: the plan indicates them.

Both are natural, depending on context.

A rough pronunciation guide:

• la planimetria ≈ lah plah-nee-meh-TREE-ah
• mostra ≈ MOH-strah
• due ≈ DOO-eh
• vie ≈ VEE-eh
• di ≈ dee
• fuga ≈ FOO-gah

A useful point: due and vie each have two vowel sounds, so they are not pronounced like a single English vowel.

Its basic meaning is two.

So here:

• due vie di fuga = two escape routes

In some informal contexts, numbers can feel a bit loose in translation, but grammatically due specifically means two, not just some.

Yes, absolutely.

This sentence sounds natural in:

• building maps
• evacuation plans
• safety documents
• architectural or technical descriptions

Planimetria is especially common in formal, technical, or building-related contexts, so the whole sentence has a practical, official feel.
