decorridas

Decorridas is the feminine plural form of the past participle of the Portuguese verb decorrer and functions as an adjective to denote time that has elapsed. It is used to describe periods or intervals that have passed, and it agrees with feminine nouns, as in as décadas decorridas or as horas decorridas.

The masculine form of the participle is decorridos, used with masculine nouns such as os anos decorridos. Decorridas therefore appears in contexts where the noun it modifies is feminine, and it is common in formal or literary writing to emphasize elapsed time or historical progression.

Etymologically, decorrer comes from Latin decurrere, meaning to run down or to pass by. In modern Portuguese, decorridas is a standard grammatical form for discussing elapsed durations and is frequently found in biographical summaries, historical overviews, and reports that aim to reflect on what has occurred over a given period.

Usage notes indicate that while decorridas is appropriate for feminine nouns, speakers may prefer simpler phrases like já se passaram or os anos que passaram in everyday speech. Decorridas should be distinguished from decorridos (masculine) and from decorrido, the past participle used in other grammatical constructions to indicate elapsed time.
