This is the 694th most frequent Portuguese word.
detido
"Detido" means "detained" or "arrested" in English.
Here, "detido" is used in its legal sense, meaning someone has been apprehended by law enforcement authorities.
O homem foi detido pela polícia.
The man was detained by the police.
In this sentence, "detido" is used metaphorically to indicate being delayed or impeded due to a situation.
Fiquei detido no trânsito por horas.
I was held up in traffic for hours.
This use of "detido" describes being engrossed or preoccupied mentally, deviating from the literal detention meaning.
