<p>The directions say write in English, but is it feasible to use Latin terms such as "de facto" or "ex post facto" etc...?</p>
<p>those terms are english as they have been borrowed from latin. They are permissible just as bon appetit and laissez-faire are considered english</p>
<p>yea, i use french myself all the time too…like coup de grace and femme fatale</p>
