Perdedor vs. derrotado
In Portuguese, both perdedor and derrotado translate to loser, but they carry distinct nuances. Perdedor is a general term describing the person or team that did not win. Derrotado is more specific, referring to someone who has been beaten, vanquished, or overpowered by an opponent.
Perdedor
A2This word focuses on the subject who failed to secure a victory. It is the direct antonym of ganhador (winner). It is often used to identify the statistics of a game or to describe a person's attitude toward losing.

Derrotado
B1This word comes from the verb derrotar (to defeat). It focuses on the state of having been beaten by someone else. It often carries a heavier emotional weight, describing the feeling of being conquered or the condition of the athlete or team after a loss.

(The defeated fighter left the ring in silence.)

Summary
Use perdedor to simply identify who didn't win or to describe behaviors (like a sore loser). Use derrotado when you want to emphasize that someone was beaten by an opponent or to describe the emotional state of being vanquished.
