EtymologyEdit

1706, from French crucial, a medical term for ligaments of the knee (which cross each other), from Latin crux, crucis (cross) (English crux), from the Proto-Indo-European *(s)ker- (to turn, to bend).

The meaning “decisive, critical” is extended from a logical term, Instantias Crucis, adopted by Francis Bacon in his influential Novum Organum (1620); the notion is of cross fingerboard signposts at forking roads, thus a requirement to choose. Specific quote is:[1]

Inter praerogativas instantiarum, ponemus loco decimo quarto Instantias Crucis; translato vocabulo a Crucibus, quae erectae in biviis indicant et signant viarum separationes.
