jeopardous
Inviting serious harm
Jeopardous means dangerous or risky—likely to cause harm or loss.
The word is rare and archaic, having been largely displaced by *jeopardizing* or simply *dangerous*: a jeopardous undertaking, jeopardous to one's health.
It appears occasionally in legal or literary contexts where an old-fashioned tone is desired.
