If an English speaker says someone is jolly, that means they are cheerful or friendly. But in French, jolie means someone is good-looking or pleasant to look at. In any case, both are nice things to say to someone .
"Um ein, sum tosar enskt, sigur, at onkur er "jolly", merkir tað, at tey eru kát ella vinarlig. Men á fronskum merkir "jolie", at onkur er vakur ella dámligur at líta á. Í hvussu er, so eru bæði góð orð at siga við onkran."
