Etymology

Diethylstilbestrol comes from parts that tell its chemistry: di- meaning 'two', ethyl meaning 'a small chemical group', and stilbestrol showing it acts like estrogen ('female hormone'). So, diethylstilbestrol is a man-made estrogen, which is why it was used in medicine and in animal feed.
