crucial

cru·cial / ˈkroōshəl/ • adj. decisive or critical, esp. in the success or failure of something: negotiations were at a crucial stage. ∎  of great importance: this game is crucial to our survival. DERIVATIVES: cru·ci·al·i·ty / ˌkroōshēˈalitē/ n. cru·cial·ly adv. ORIGIN: early 18th cent. (in the sense ‘cross-shaped’): from French, from Latin crux, cruc- ‘cross.’ The sense ‘decisive’ is from Francis Bacon's Latin phrase instantia crucis ‘crucial instance,’ which he explained as a metaphor from a crux or fingerpost marking a fork at a crossroad; Newton and Boyle took up the metaphor in experimentum crucis ‘crucial experiment.’
