tritos marks what stands third in a sequence, a time reckoning, or a stated one-third portion.

The term most often marks a third point in time, including a day, hour, watch, or repeated occasion; it also identifies the third member of an ordered series and, in several Revelation scenes, a one-third portion of a larger whole.

1. Third point in time or repeated occurrence · dominant

   In 1 Corinthians 15:4 the dative feminine form occurs in the clause the APB renders “on the third day,” while 2 Corinthians 12:14 uses the accusative neuter form for the APB’s “third time.” John 21:17 likewise places the form with a third asking of the same question, and Acts 23:23 locates the soldiers’ departure from the third hour of the night.

   1 Corinthians 15:42 Corinthians 12:14John 21:17Acts 23:23Luke 12:38Matthew 26:44
2. Third member in an ordered series · common

   The form identifies a position after first and second members: 1 Corinthians 12:28 places teachers after apostles and prophets, and Revelation 21:19 names the third foundation after jasper and sapphire. In Revelation 14:9, the APB renders the clause “another angel, a third, followed them.”

3. A one-third portion · occasional

   In Revelation 8:7, the neuter form occurs in statements that a third of the earth and trees was burned. Revelation 8:12 repeats the construction for portions of the sun, moon, stars, day, and night, and Revelation 9:15 describes the killing of a third of humanity.

In the Anselm Project Bible: The APB commonly presents the term with “third” in expressions such as “third day,” “third hour,” and “third time,” and with “a third of” where a portion is in view. These renderings reflect the clauses as a whole rather than a fixed English equivalent for every form.
