Fatais

Fatais is the plural form of the Portuguese adjective fatal, meaning deadly or causing death. In singular form, the word is fatal; fatais describes plural nouns and agrees in gender and number with them. For example, danos fatais (fatal damages), ferimentos fatais (fatal injuries), acidentes fatais (fatal accidents).

Etymology and meaning: fatal derives from Latin fatalis, related to fatum meaning fate or doom. Through Latin and Old French practices, the word entered Portuguese with the sense of destined to cause death or resulting in death. The plural form fatais is used for both masculine and feminine nouns in everyday and formal writing.

Usage: fatais is used to characterize outcomes, events, or conditions that result in death or are lethal. It appears in news reports, medical and legal language, and formal prose. It is not a noun, but rather an adjective that can modify plural nouns. Examples include “casos fatais,” “efeitos fatais,” and “consequências fatais.” The term is common in neutral or technical contexts and is typically contrasted with non-fatal or mild descriptions.

See also: fatalidade (the noun meaning fatality or fatal outcome), fatalismo (a philosophical notion related to fate), and related adjectives such as fatal, fatalmente (adverbs in Portuguese are used with different forms).

Note: While fatais is widely understood in Portuguese-speaking contexts, it is not used as a standalone noun and should be placed before or after the noun it modifies, following standard Portuguese agreement rules.
