Questions & Answers about A declaração pré-preenchida mostra a fonte pagadora.

Why is it a declaração and not o declaração?

Because declaração is a feminine noun in Portuguese, so it takes the feminine singular article a.

A few related points:

• a = the for feminine singular nouns
• o = the for masculine singular nouns
• nouns ending in -ção are very often feminine:
  
  • a declaração
  • a informação
  • a situação

So a declaração is simply the correct gender/article combination.

What does pré-preenchida mean, and why is it written with a hyphen?

Pré-preenchida means pre-filled or already filled in beforehand.

It is made of:

• pré- = pre-
• preenchida = filled in

The hyphen is used because the prefix pré- keeps its stress and accent in this form. In standard spelling, forms with pré- like this are commonly hyphenated:

• pré-pago
• pré-natal
• pré-preenchido / pré-preenchida

So declaração pré-preenchida means pre-filled tax return / pre-filled declaration.

Why does it say pré-preenchida and not pré-preenchido?
