Webster's 1913 Dictionary
\In*fin"i*ty\, n.; pl. {Infinities}. [L. infinitas;
pref. in- not + finis boundary, limit, end: cf. F.
infinit['e]. See {Finite}.]
1. Unlimited extent of time, space, or quantity; eternity;
   boundlessness; immensity. --Sir T. More.

         There can not be more infinities than one; for one
         of them would limit the other.        --Sir W.

2. Unlimited capacity, energy, excellence, or knowledge; as,
   the infinity of God and his perfections. --Hooker.

3. Endless or indefinite number; great multitude; as an
   infinity of beauties. --Broome.

4. (Math.) A quantity greater than any assignable quantity of
   the same kind.

Note: Mathematically considered, infinity is always a limit
      of a variable quantity, resulting from a particular
      supposition made upon the varying element which enters
      it. --Davies & Peck (Math. Dict.).

5. (Geom.) That part of a line, or of a plane, or of space,
   which is infinitely distant. In modern geometry, parallel
   lines or planes are sometimes treated as lines or planes
   meeting at infinity.

{Circle at infinity}, an imaginary circle at infinity,
   through which, in geometry of three dimensions, every
   sphere is imagined to pass.

{Circular points at infinity}. See under {Circular}.

Computing Dictionary

1. The size of something infinite.

Using the word in the context of sets is sloppy, since different infinite sets aren't necessarily the same size cardinality as each other.
