Venturesome is an adjective that means willing to take risks.
Coming from Middle English, the word venture is an abbreviated version of ‘adventure,’ or exciting hazardous activity. The suffix SOME means ‘characterized by being.’ We see it in words like ‘tiresome,’ ‘fearsome’ and our word of the day venturesome. Here’s an example of it in use:
I wasn’t what you’d call a venturesome child. My idea of taking risks was riding my bike across the street without the training wheels.
