Definition: "DPT" in Greek has no clear translation, but "dpt4" seems to be a Greek prefix meaning "fourth." The precise term would depend on how this suffix is used or if it refers specifically to a fourfold descent. For instance, it might refer to an odd number of people who share the same parents or a specific form of a disease where there are four times as many cases compared to three.
