Controversy is a state of prolonged public dispute or debate, usually concerning a matter of opinion. The word was coined from the Latin controversia, as a composite of controversus – "turned in an opposite direction," from contra – "against" – and vertere – to turn, or versus (see verse), hence, "to turn against."
The most contentious or well known subjects, topics or areas are politics, religion and sex.Other areas of controversy include history and philosophy. Other minor yet prominent areas of controversy are economics, science, finances, culture, education, the military, society, celebrities, organisation, the media, age, gender, and race. Controversy in matters of theology has traditionally been particularly heated, giving rise to the phrase odium theologicum. Controversial issues are held as potentially divisive in a given society, because they can lead to tension and ill will, as a result they are often taboo to be discussed in the light of company in many cultures.
