Temerarious is an adjective that means ‘reckless or rash.’
Our word of the day comes directly from the Latin word for ‘rashly.’ It’s been around since the mid-16th century. Here’s an example of it in use:
As a kid, my temerarious behavior was a problem from time to time. Throwing a tantrum because you didn’t get what you wanted was, in my house, the best way to get grounded for a week.
