Summary: The Latin root word *voc* and its variant *vok* both mean "call." These roots are the word origins of a fair number of English vocabulary words, including [*voc*]al, [*voc*]abulary, in[*vok*]e, and pro[*vok*]e. The roots *voc* and *vok* are easily recalled through the words [*voc*]al, of "calling," and re[*vok*]e, to "call" back.
