O técnico verificou a instalação elétrica e repô-la.

Verificou is the 3rd person singular of the preterite of verificar. In plain English terms, it is a simple past form: the technician checked/inspected something as a completed action in the past.

The subject is O técnico.

In this sentence, it is most naturally understood as a past tense form:

• repôs + a → repô-la

So the structure is:

• verificou = he checked
• repô-la = and restored/put it back

That matches the first verb nicely.

A tricky point: repô-la can also be the spelling of:

• repor + a = to restore it

So by itself, the form is ambiguous. But in this sentence, context strongly points to the past tense reading.

Because Portuguese writes many object pronouns attached to the verb with a hyphen when they come after the verb. This is called enclisis.

So instead of writing the pronoun separately, Portuguese writes:

• repô-la

not:

• repô la

This is very normal in European Portuguese.

Because -la is the direct object pronoun referring back to a instalação elétrica.

Since a instalação elétrica is:

• feminine
• singular

the matching direct object pronoun is a = it.

When that pronoun attaches to a verb ending in -r, -s, or -z, it changes to:

• -la

So here, a instalação elétrica is not repeated; it is replaced by the pronoun -la.

Because Portuguese spelling changes when o/a/os/as attach to a verb ending in -r, -s, or -z:

1. the final -r, -s, or -z drops
2. o/a/os/as becomes lo/la/los/las

So:

• repôs + a → repô-la
• repor + a → repô-la

That is why:

• repôs-a is not the standard form
• repor-la is also not the standard form

The written result is repô-la.

The circumflex in pô helps preserve the correct stressed vowel after the ending changes.

It is the same kind of pattern you see in forms like:

• pôr → pô-lo
• fazer → fazê-lo

So the accent is not random; it is part of the correct written form after the pronoun is attached.

No.

• In a instalação elétrica, a is the definite article = the
• In repô-la, -la contains the direct object pronoun a = it

So they may look related, but they do different jobs:

• a instalação elétrica = noun phrase with article
• repô-la = verb + attached pronoun

Because in Portuguese, adjectives often come after the noun, especially when they are classifying or technical.

So:

• instalação elétrica

is the normal order for electrical installation.

This is very common in Portuguese technical vocabulary.

Yes. In European Portuguese, in a neutral affirmative clause, object pronouns often come after the verb.

So e repô-la is the normal standard pattern here.

A version like:

• e a repôs

would not be the neutral standard choice in this context.

This is one of the areas where European Portuguese strongly prefers attached pronouns more than English speakers may expect.

Roughly, you can think of it as:

• reh-POH-luh

with the stress on pô.

In European Portuguese, the unstressed vowels are usually reduced, so the real pronunciation is more compact than that English-style guide suggests. The important point for a learner is:

• stress on pô
• pronounce la clearly as the attached pronoun
