Affinity


Definition:

  • (n.) Kinship generally; close agreement; relation; conformity; resemblance; connection; as, the affinity of sounds, of colors, or of languages.
  • (n.) Companionship; acquaintance.
  • (n.) That attraction which takes place, at an insensible distance, between the heterogeneous particles of bodies, and unites them to form chemical compounds; chemism; chemical or elective affinity or attraction.

Infinity


Definition:

  • (n.) Unlimited extent of time, space, or quantity; eternity; boundlessness; immensity.
