fateful

Synonym discussion
Sense: adjective/1
All five words describe events or choices that carry great importance, but they differ in connotation and scope. Fateful is the only one that strongly implies a negative or tragic outcome — a fateful day is one you wish had never come. Decisive focuses on settling an issue once and for all (a decisive battle, a decisive vote) and is neutral in tone. Momentous emphasises historical significance without specifying whether the result is good or bad (a momentous discovery in medicine). Critical highlights urgency and the risk of failure (a critical stage of the illness), making it more dramatic than the others. Pivotal suggests that everything else depends on this single element (a pivotal witness in a trial). Example: 'The general's fateful decision cost thousands of lives' would sound odd if you replaced fateful with momentous, because momentous lacks the sense of doom.

Etymology
Fateful comes from the noun fate (from Latin fatum, meaning 'that which has been spoken or decreed by the gods') plus the suffix -ful ('full of'). The word entered English in the early 1700s and originally carried the strong sense of something determined by destiny. Over time, it developed two additional branches: one pointing to ominous signs of disaster (mid-1800s) and one highlighting a decisive turning point regardless of supernatural causes (late 1800s).
