Proeza is a feminine noun that means do something unusual, difficult or never done before. It is also used ironically when someone does something really stupid or shameful.
As in the sentences:
"She was the first woman to reach this position, it was a real feat in a market taken over by men.".
Or ironically: "It was just me and the ball, in front of the goal, and I did the greatest feat of all: I kicked it out".
Doing or committing a feat is achieving something at a high level of difficulty. It is something extraordinary, not a mere action, it is an achievement worthy of recognition.
A feat needs courage to be performed, like a heroic act. Except for the accidental feats that would fall under the ironic use of the term.
Among the historical feats accomplished we can list the Discovery of America, by Christopher Columbus, having been the first European to officially disembark in American lands, which characterizes a feat.
Already in the feats of the Brazilian people, one can mention the achievements of Santos Dumont. The aviator circled the Eiffel Tower with his airship in 1901, and became one of the most famous people in the world at that time.
The word feat has how synonyms the terms feat, feat, achievement, bravery, heroism, success, adventure, and bravery.
