Inclined or willing to incur hazard or engage in adventures; bold to encounter danger; daring; venturesome; courageous; enterprising.Full of hazard; attended with risk; exposing to danger; requiring courage; hazardous: as, an adventurous undertaking.Synonyms Adventurous, Enterprising, Rash, Reckless, Foolhardy, venturesome, venturous. The adventurous man incurs risks from love of the novel, the arduous, and the bold, trusting to escape through the use of his bodily and mental powers; he would measure himself against difficult things. When this spirit does not go so far as to deserve the name of rashness or foolhardiness, it is considered a manly trait. The enterprising man is alert to undertake new and large things, not necessarily involving risk; he is constantly breaking out of routine. The rash man hastens to do a thing with little thought of the consequences, and generally in the heat of feeling. With the foolhardy man the risks are so great and the absence of thought is so entire that he seems to have the hardihood of the fool. The reckless man has the impetuosity of the rash man, but he is more careless of consequences. The rash man is too precipitate; the reckless man shows temerity; the foolhardy man is careless or defiant even when he undertakes the impossible.
