What is the compound of 'Fools rush in where angels fear to tread.'

Answer: People without experience rush into situations which experienced people normally avoid.

Explanation:

The meaning of this line is that people who have certain experience avoid situations which inexperienced people rush into. The line originates from Alexander Pope's poem - An Essay on Criticism. In the line, Pope refers to experienced people as "angels", and inexperienced as "fools." Inexperienced people lack judgment and caution that wise people have.
