Etymology
Origin of perilous
First recorded in 1250–1300; Middle English, from Anglo-French perillous, from Latin perīculōsus; see peril, -ous
Explanation
Something that is dangerous or very risky can be described with the adjective perilous. If you are driving in a blizzard, you may kick yourself for making such a perilous journey. The adjective perilous comes from the Latin word periculum, meaning dangerous. Words from the same root include peril, a noun meaning a dangerous situation, and imperil, a verb meaning to put in danger. The last thing you want to do as a parent is to imperil your children. Unfortunately, childhood is filled with peril — from climbing on the monkey bars to eating paste, dirt, or bugs. If you think you can prevent all perilous situations, you haven't been a parent very long!
