Revisamos el regloscopio y la carrocería.

Spanish often drops subject pronouns because the verb ending already tells you who the subject is.

• Revisamos = we check / we inspect or we checked / we inspected
• So nosotros is usually unnecessary unless you want emphasis or contrast.

A fuller version would be:

• Nosotros revisamos el regloscopio y la carrocería.

But in normal Spanish, leaving out nosotros sounds more natural.

It can mean either one.

For -ar verbs, the 1st person plural form is the same in:

• the present: we check / we inspect
• the preterite: we checked / we inspected

So:

• Revisamos el regloscopio y la carrocería.
  can mean either
  We inspect/check the regloscope and the bodywork
  or
  We inspected/checked the regloscope and the bodywork.

Context tells you which meaning is intended.

Not usually.

In Spanish, revisar often means:

• to check
• to inspect
• to examine
• to look over

So in this sentence, revisamos is more like we inspect/check, not we revise in the English sense of editing or rewriting something.

This is a very common point for English speakers because revisar looks like a cognate, but its most common everyday meaning is different.

Because Spanish nouns have grammatical gender, and the article has to match the noun.

• el regloscopio → masculine
• la carrocería → feminine

So the sentence uses:

• el for the masculine noun
• la for the feminine noun

The gender is something you usually learn with the noun itself.

In Spanish, articles are used more often than in English, especially with concrete nouns.

So Revisamos el regloscopio y la carrocería sounds natural because it refers to specific things being inspected.

Without the articles, the sentence would sound unnatural in standard Spanish in this context.

Regloscopio is a technical automotive term. It refers to a device used to check or align headlights.

So this is not a common everyday household word; it is the kind of word you might hear in:

• a garage
• a vehicle inspection centre
• a mechanic’s workshop

That is why the whole sentence sounds like something from an automotive inspection context.

Carrocería means the bodywork or body of a vehicle — basically the outer structure/panels, not the engine or internal mechanical parts.

So it refers to things like:

• dents
• paint
• panels
• exterior condition

In a car-related context, it is a very common word.

In Spain Spanish, it is pronounced roughly like:

• ca-rro-the-RI-a

A few key points:

• rr is a rolled/trilled r
• the c before e is usually pronounced like th in think in most of Spain
• the written accent on í shows that the stress falls there: carrocerí**a

So the stressed syllable is:

• carrocerÍa

Here y means and, and it is pronounced like ee.

So:

• el regloscopio y la carrocería

sounds roughly like:

• el regloscopio ee la carrocería

In connected speech it is short and unstressed.

Spanish normally uses y for and.

It changes to e only before a word that begins with an i- or hi- sound, to avoid an awkward repetition of the same sound.

For example:

• padre e hijo
• España e Italia

But here the next word is la carrocería, which does not begin with an i sound, so y is correct.

Yes. It sounds natural, especially in a technical or automotive inspection context.

• revisamos is a normal verb choice for check/inspect
• carrocería is standard Spanish
• regloscopio is technical, but correct in the right setting

So the sentence sounds like something you might read in:

• a workshop checklist
• a mechanic’s report
• a vehicle inspection procedure
