The Free On-line Dictionary of Computing (30 December 2018):

class

   1.  The prototype for an object in an
   object-oriented language; analogous to a derived type in a
   procedural language.  A class may also be considered to be a
   set of objects which share a common structure and behaviour.
   The structure of a class is determined by the class
   variables which represent the state of an object of that
   class and the behaviour is given by a set of methods
   associated with the class.

   Classes are related in a class hierarchy.  One class may be
   a specialisation (a "subclass") of another (one of its
   "superclasses") or it may be composed of other classes or it
   may use other classes in a client-server relationship.  A
   class may be an abstract class or a concrete class.

   See also signature.

   2.  See type class.

   3.  One of three types of Internet addresses
   distinguished by their most significant bits.

   3.  A language developed by the Andrew Project.
   It was one of the first attempts to add object-oriented
   features to C.

Bouvier's Law Dictionary, Revised 6th Ed (1856):

CLASS. The order according to which are arranged or distributed, or are
supposed to be arranged or distributed, divers persons or things; thus we
say, a class of legatees.
     2. When a legacy is given to a class of individuals, all who answer the
description at the time the will takes effect, are entitled; and though the
expression be in the plural, yet if there be but one, he shall take the
whole. 3 M'Cord, Ch. R. 440.
     3. When a bond is given to a class of persons, it is good, and all
composing that class are entitled to sue upon it; but if the obligor be a
member of such class, the bond is void, because a man cannot be obligor and
obligee at the same time; as, if a bond be given to the justices of the
county court, and at the time the obligor is himself one of said justices. 3
Dev. 284, 287,289; 4 Dev. 882.
     4. When a charge is made against a class of society, a profession, an
order or body of men, and cannot possibly import a personal application to
private injury, no action lies; but if any one of the class have sustained
special damages in consequence of such charge, he may maintain an action. 17
Wend. 52, 23, 186. See 12 John. 475. When the charge is against one of a
class, without designating which, no action lies; as, where three persons
had been examined as witnesses, and the defendant said in addressing himself
to them, "one of you three is perjured." 1 Roll. Ab. 81; Cro. Jac. 107; 16
Pick. 132.
