Revisamos el código GC y el camuflaje.

Because in Spanish, the nosotros form of many -ar verbs is identical in the present and the preterite.

So revisamos can mean:

• we review / we check
• we reviewed / we checked

You usually tell which one it is from the context, time words, or the surrounding sentences.

For example:

• Hoy revisamos el código. = Today we’re checking/reviewing the code.
• Ayer revisamos el código. = Yesterday we checked/reviewed the code.

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

Here, revisamos already means we. So:

• Revisamos el código GC y el camuflaje.
• Nosotros revisamos el código GC y el camuflaje.

Both are grammatical, but the version without nosotros is more natural unless you want emphasis or contrast.

For example:

• Nosotros revisamos el código; ellos revisan el diseño.

There, nosotros is useful because it contrasts with ellos.

Here revisar means something like:

• to review
• to check
• to inspect
• to go over

It is a very common verb in Spanish and usually takes a direct object with no preposition:

• revisar el código
• revisar el informe
• revisar el coche

So in this sentence, it simply means that we check/review those things.

Because Spanish often repeats the definite article when talking about two separate definite nouns.

So:

• el código GC y el camuflaje

sounds natural because you are referring to the GC code and the camouflage as two distinct things.

In English, we often use the only once before two nouns, but Spanish often repeats it more than English does.

If you said el código GC y camuflaje, it would usually sound less natural here.

Here GC is acting like a label or identifier attached to código.

So código GC works like:

• the GC code
• the code called GC
• the GC code/system/code label, depending on context

Spanish often puts a noun first and then an abbreviation, acronym, or label after it:

• el protocolo HTTP
• el formato PDF
• el archivo XML

So código GC follows a common pattern.

Because the stress falls on the third-to-last syllable: CÓ-di-go.

Spanish spelling rules say that words stressed on the antepenultimate syllable must have a written accent mark.

So:

• código → stress on có
• therefore it needs the accent

Without the accent, Spanish readers would expect a different stress pattern.

Because camuflaje is a masculine noun.

Its grammatical gender is masculine, so it takes:

• el camuflaje
• un camuflaje

This is normal for many nouns ending in -aje, which are usually masculine:

• el viaje
• el mensaje
• el paisaje
• el camuflaje

So even though noun gender can feel arbitrary to English speakers, this one follows a common pattern.

Yes, y changes to e before a word that begins with an i sound.

For example:

• padres e hijos
• España e Italia

But here the next word is el, which begins with an e sound, not an i sound, so it stays y:

• el código GC y el camuflaje

So y el is correct.

No. The personal a is only used before specific human direct objects, and sometimes pets or personified beings.

Here the direct objects are things:

• el código GC
• el camuflaje

So you simply say:

• Revisamos el código GC y el camuflaje.

Not:

• Revisamos a el código...

That would be incorrect.

In standard Peninsular Spanish, it would be approximately:

• revisamos → reh-bee-SA-mos
• el código → el CO-dhee-go
• camuflaje → kah-moo-FLA-heh

A few useful notes for Spain:

• v in revisamos is pronounced like a soft Spanish b
• d in código is often softer than English d
• j in camuflaje is pronounced like a strong throaty h
• c before o in código is a hard k sound

So the full sentence is roughly:

reh-bee-SA-mos el CO-dhee-go GC ee el kah-moo-FLA-heh

The exact sound of GC depends on whether the speaker reads the letters individually or treats them as a known abbreviation.
