What's the difference between affinity and origin?

Affinity

  • (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.
