Here is a worksheet on the Greek roots gon/o and -gony. They mean reproduction, origination, and generation. Unsurprisingly, then, you’ll find gon/o at the base of gonad. Otherwise, besides cosmogony, (and, alas, gonorrhea ) the words on this worksheet are all new to me. If the book from which they are drawn is believable, these are words that will turn up on the SAT.
