While reading history text online, I find that some dates have a prefix e.g.

  • c. 5000 BP
  • c. 3300 BCE
  • ca. 3300 BC

What does the prefix mean?

  • @jwenting I disagree. It is relevant to this site, however simple. – called2voyage May 13 '14 at 16:51
  • @called2voyage the term is relevant, the explanation of it off topic. – jwenting May 13 '14 at 17:10
  • On second thought, it is general reference even though I would consider it on topic otherwise. – called2voyage May 13 '14 at 17:22
  • As the person asking this question, both the prefix (c. ca.) and postfix (BP, BC, BCE) did not look like words to me. It is similar to the "$" in $2500. Furthermore, some (Wikipedia) say "Circa is widely used in genealogy and historical writing". So I feel this should be more on-topic than not. – Jake May 16 '14 at 1:41

c or ca means circa, which means approximately.
