In Latin, fatum—“that which is spoken”—is the word that gives us the modern concept of fate. The noun comes from fari, a verb meaning “to speak,” so its earliest sense suggests a divine utterance, prophecy, or decree that has been spoken and therefore must come to pass.
In Roman thought, fatum could mean an individual destiny, a prophetic pronouncement, or the larger order governing events. Its plural, fata, could refer to the decrees of fate or the Fates themselves. The related adjective fatalis produced English words such as “fatal,” meaning connected with fate or destined to end in disaster.
Fatum was not identical to Fortuna. Fortuna represented luck, chance, prosperity, or the unpredictable turns of fortune, while fatum emphasized an ordained outcome. Omen was a sign that might reveal what was coming; fatum was the destiny or authoritative pronouncement itself.
Roman philosophers debated whether fate left room for human freedom. Cicero’s treatise De fato, written in 44 BC, examines that problem and weighs deterministic arguments against the possibility of free will.
