"O teclado fica sujo rápido."

Translation: The keyboard gets dirty fast.

[vam1980]

Is 'teclado' a keyboard from a computer or the musical instrument (or both)?

[snoipah]

Both

[ajvincent]

I think "gets dirty fast" sounds strange in English - it should be the adverb "quickly"

[GidgetGilda]

Whether or not a person says "gets dirty rapidly" "gets dirty fast" or "gets dirty quickly" differs by region. I hear all of those used regularly.

[KPThomson]

I completely agree.

[Juknow92]

Well, quickly is not excepted

[AlfieValera]

Fica means is/stay right. So can it also mean gets? In what context?

[Paulenrique]

it means "to get" when it has the sense of "to become".

[bbeeco]

Can you give a few examples?

[BenHueb]

I believe this was from the lesson on colors:
Ele fica amarelo.

[Danmoller]

Ser vs ficar vs estar

[Jonathanchlj]

"Rápido" seems strange here to me, shouldn't it be an adverb like "rapidamente"? I know that I'm probably wrong, but In French and it Italian it should be rapidement/rapidamente.

[PHScanes]

In this case, rápido and rapidamente are the same adverb
