What's the difference between approximation and propinquity?

Approximation


Definition:

  • (n.) The act of approximating; a drawing, advancing or being near; approach; also, the result of approximating.
  • (n.) An approach to a correct estimate, calculation, or conception, or to a given quantity, quality, etc.
  • (n.) A continual approach or coming nearer to a result; as, to solve an equation by approximation.
  • (n.) A value that is nearly but not exactly correct.

Propinquity


Definition:

  • (n.) Nearness in place; neighborhood; proximity.
  • (n.) Nearness in time.
  • (n.) Nearness of blood; kindred; affinity.

Example Sentences:

  • (1) As the excitable narrator said: “It will attract young men with bright new ideas.” This was to be a radically decentralised city, inspired by Californian urban theorist Melvin Webber, who believed that the traditional concentric city would be superseded by “community without propinquity”: closely bonded without being physically crammed together, a vision which looks rather like the internet age.
  • (2) For propinquity may be enforced, but affection cannot.
  • (3) His rich vocabulary , including such rarely used words as "bailiwick", "condign", "propinquity" and "occlude", lifted the tone of the long sessions before Lord Justice Leveson.
