✕Common Mistakes

  • Pra que será um DEA?

    "Será" is the future of "ser" and changes the meaning; the correct verb is "serve" (to be used for).

  • Pra que serve um D.E.A?

    When writing the acronym, do not separate the letters with periods; write "DEA" as a single block.

  • Pra que serve um DEAs?

    The noun is singular; the plural would be "DEAs" only when referring to multiple devices, not in this question.

Cultural Tip

In Brazil, DEAs are increasingly installed in schools, gyms, shopping centers and even some workplaces. When you ask about the device in a formal setting (e.g., a hospital), prefer the full form "Para que serve um DEA?". In casual conversation among friends, the shortened "Pra que serve um DEA?" sounds natural and friendly.
