This time im gonna show you the infographic about the origin of the name of the characters in Dragon Ball series, and dont worry this is from trusted material source.
Did you know that Akira Toriyama (the mangaka / creator of Dragon Ball) gave dragon balls characters name, particularly their original Japanese name, from a pun on regular words, often the names of various foods?
Saiyans itself is taken from Japanese word Yasai which means vegetable therefore the characters which are included in Saiyan tribe had been named from various vegetables. For examples Kakarot (Gokus real name on the Saiyans planet) is taken from the word carrot and Vegeta, the prince of the Saiyans is derived from "vegetables".

Ok thats all for Dragon Ball Z Character Secret Origins today guys. See ya :D
