Etymology
Origin of sin1
First recorded before 900; Middle English noun sinne, sin(e), sen(ne), Old English syn(n) “moral or religious offense, misdeed”; akin to German Sünde, Old Norse synd, Latin sōns (inflectional stem sont- ) “guilty,” literally “that man being the one”; the verb is derivative of the noun; the Germanic and Latin forms all being present participle forms of the root es- “to be”; see origin at am ( def. )
Origin of sin2
First recorded in 1895–1900; from Hebrew śīn
Origin of sīn4
From Arabic
Explanation
You might not want to be the one at the party who takes the last piece of cake, but then again, it would be a sin to let it sit there, uneaten. A sin is a deeply regrettable action. The most common definition of sin is religious: it's an immoral act against God or divine law. Any serious offense, even if it's not religious, can be called a sin, and so can something less serious if you're talking about it in a joking way, as in, "You've got to buy those shoes — it would be an absolute sin not to." In math, sin is the abbreviation of sine, the trigonometric function.
