The word dogmatic traces back to Greek dogmatikos, derived from dogma (opinion/decree), which itself comes from dokein (to seem/to think). The root dog- reflects rigid belief, while -matic (via Greek -matikos) denotes systematic learning. Over time, the term evolved from "philosophically doctrinal" to its modern sense of "uncompromisingly authoritative."
