A temptation is an act that looks appealing to an individual. It is usually used to describe acts with negative connotations and as such, tends to lead a person to regret such actions, for various reasons: legal, social, psychological (including feeling guilt), health, economic, etc. Temptation also describes the coaxing or inducing a person into committing such an act, by manipulation or otherwise of curiosity, desire or fear of loss.
Though at present used in many non-religious connotations, the term has implications deeply rooted in Judaism and the The Old Testament, starting with the story of Eve and the original sin. Many non-Western cultures had no precise equivalent until coming into contact with Europeans; for example, Jesuit missionaries in Brazil, translating the Lord's Prayer into Old Tupi, had to use the Portuguese word tentação, since Tupi had no word expressing "temptation" in that sense (see Old Tupi language#Sample text).
