Meaning of 'Pros and cons'

Pros and cons are arguments for or against a particular issue. Pros are arguments which aim to promote the issue, while cons suggest points against it. The term has been in use since the 16th century and is a shortening of a Latin phrase, pro et contra, which means “for and against.” Considering the pros and cons of an issue is a very useful way to weigh the issue thoughtfully and reach an informed decision.
