Kai (conjunction)

Και ("and") is a conjunction in Greek (sometimes abbreviated k), Coptic and, under the form kaj, Esperanto.

Kai is the most frequent word in any Greek text and thus used by statisticians to assess authorship of ancient manuscripts (see below).

Authorship of ancient texts

The number of common words which express a general relation ("and", "in", "but", "I", "to be") is random with the same distribution at least among the same genre. By contrast, the occurrence of the definite article "the" cannot be modeled by simple probabilistic laws because the number of nouns with definite article depends on the subject matter.

Table 1 has data about the epistles of St. Paul. Abbreviations: Rom Romans; Co1 1st Corinthians; Co2 2nd Corinthians; Gal Galatians; Phi Philippians; Col Colossians; Th1 1st Thessalonians; Ti1 1st Timothy; Ti2 2nd Timothy; Heb Hebrews. 2nd Thessalonians, Titus, and Philemon were excluded because they were too short to give reliable samples. From an analysis of these and other data [Mor65, p. 224] the first 4 epistles (Romans, 1 Corinthians, 2 Corinthians, and Galatians) form a consistent group, and all the other epistles lie more than 2 standard deviations from the mean of this group (using X2 statistics). If Paul is defined as being the author of Galatians, then he also wrote Romans and 1st and 2nd Corinthians. The remaining epistles come from at least six hands.
