What's the difference between affinity and task?

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.
  • (n.) A relation between species or highe/ groups dependent on resemblance in the whole plan of structure, and indicating community of origin.
  • (n.) A superior spiritual relationship or attraction held to exist sometimes between persons, esp. persons of the opposite sex; also, the man or woman who exerts such psychical or spiritual attraction.
