Hidroizolația este în deviz.

Because Romanian often puts the definite article at the end of the noun instead of using a separate word like English the.

• hidroizolație = waterproofing / hydro-insulation
• hidroizolația = the waterproofing

So in this sentence, hidroizolația means the waterproofing.

This is very common in Romanian:

• casă = house
• casa = the house

It is the subject of the sentence.

Structure:

• Hidroizolația = the waterproofing
• este = is
• în deviz = in the estimate / quote / costing document

So the sentence is built like:

Subject + verb + prepositional phrase

Este means is. It is the 3rd person singular form of the verb a fi (to be).

Examples:

• este = he/she/it is
• Hidroizolația este... = The waterproofing is...

It is used exactly like English is in this sentence.

No. In Romanian, the verb a fi does not change for gender, only for person and number.

So:

• El este = He is
• Ea este = She is
• Hidroizolația este = The waterproofing is

Even though hidroizolația is feminine, the verb still stays este.

In this context, deviz usually means something like:

• estimate
• quotation
• cost estimate
• itemized cost document

This is especially common in construction, renovation, and technical work.

So în deviz often means that something is included in the quoted estimate / costing document.

Because deviz here is being used in a more general or document-type sense, similar to saying:

• It is in the estimate
• It appears in the quote
• It is included in the costing

If you wanted to say in the specific estimate, you could say:

• în devizul acesta = in this estimate
• în devizul final = in the final estimate

So:

• în deviz = in the estimate / in the quote, more general
• în devizul ... = in the specific estimate ...

În usually means in or inside, and Romanian often uses it in a very natural way for documents, lists, plans, and estimates.

So este în deviz literally means:

• is in the estimate

But in real usage, it often implies:

• is included in the estimate
• is listed in the estimate

This is a normal Romanian way to express that something appears as part of a costed item or quoted work.

Yes. That is often the most natural interpretation in English.

Romanian says it more literally as is in the estimate, but the practical meaning is often:

• The waterproofing is included in the estimate
• The waterproofing is listed in the quote

So even if the literal wording is simple, the real meaning is often slightly broader.

Yes. That version is also correct and is a bit more explicit.

• Hidroizolația este în deviz. = The waterproofing is in the estimate.
• Hidroizolația este inclusă în deviz. = The waterproofing is included in the estimate.

The first version is shorter and very natural in context. The second version spells out the idea of inclusion more clearly.

After în, Romanian normally uses the accusative.

In this sentence, deviz is an indefinite singular noun, and for this noun the accusative form looks the same as the nominative form, so you do not see any extra change.

That is why you simply get:

• în deviz

If it were definite, you might see:

• în devizul final = in the final estimate

The normal word order is:

Subject + verb + complement

• Hidroizolația = subject
• este = verb
• în deviz = complement

So this is a very standard, neutral Romanian sentence.

You could change the order for emphasis in some contexts, but the given version is the most straightforward one.

Yes. In everyday Romanian, este is often shortened to e.

So you may hear:

• Hidroizolația e în deviz.

This means exactly the same thing and is very common in spoken language.

The full form este is a bit more formal or careful.

A helpful approximate pronunciation is:

hee-dro-ee-zo-la-tsi-a

A few useful points:

• h is pronounced
• ț sounds like ts in cats
• ia at the end is pronounced as two vowel sounds

So the ending -ția sounds roughly like -tsi-a, not like English -sha.

Approximately:

deh-veez

A few notes:

• the stress is usually on the second syllable: de-VIZ
• z is pronounced like English z

So it sounds roughly like deh-VEEZ.

Yes, it is feminine.

You can tell from the dictionary form hidroizolație and the definite form hidroizolația.

That matters for things like adjectives and participles:

• hidroizolația este inclusă
  not
• hidroizolația este inclus

because inclusă must agree with the feminine noun.

There are three very useful grammar points here:

1. Romanian definite article is attached to the noun

   • hidroizolație → hidroizolația

2. Este is the singular form of a fi

   • este = is

3. În + noun is often used for documents and lists

   • în deviz = in the estimate / included in the estimate

So this short sentence is a good example of core Romanian structure.
