Wrong.  A violation of the legal rights of another; an invasion of right to the damage of the parties who suffer it, especially a tort.  State ex rel. and to Use of Donelon v. Deuser, 345 Mo. 628, 134 S.W.2d 132, 133.  It usually signifies injury to person, property or relative noncontractual rights of another than wrongdoer, with or without force, but, in more extended sense, includes violation of contract.  Daurizio v. Merchants' Despatch Transp. Co., 152 Misc. 716, 274 N.Y.S. 174.  See Tort.

The idea of rights naturally suggests the correlative one of wrongs; for every right is capable of being violated. A right to receive payment for goods sold (for example) implies a wrong on the part of him who owes but withholds the price; a right to live in personal security, a wrong on the part of him who commits personal violence.  And therefore, while, in a general point of view, the law is intended for the establishment and maintenance of rights, we find it, on closer examination, to be dealing both with rights and wrongs.  It first fixes the character and definition of rights, and then, with a view to their effectual security, proceeds to define wrongs, and to devise the means by which the latter shall be prevented or redressed.

Private wrong.  The violation of public or private rights, when considered in reference to the injury sustained by the individual, and consequently as subjects for civil redress or compensation.  Huntington v. Attrill, 146 U.S. 657, 13 S.Ct. 224, 36 L.Ed. 1123.  See Tort.

Public wrongs.  Violations of public rights and duties which affect the whole community, considered as a community; crimes and misdemeanors.  3 Bl.COmm. 2; 4 Bl.Comm. 1.

Real wrong.  In old English law, an injury to the freehold.
