Donald: “great chief” and “ruler or king of the world.”

Trump: derived from occupational names referring to "trumpet", either for trumpeters or trumpet-makers.

Taken together, Donald Trump's name literally tells the story of a "great chief" who will have the quality of a "trumpet." Also related to the word "triumph" and "triumphant"

Fun fact: Joe Biden's name means "God shall add from the shadow valley" whatever that means.
