سه

Se anchors one of Iran's most famous landmarks: سی و سه پل (Si-o-se Pol), the 33-arch bridge in Isfahan, built in 1602. The number also appears in Sizdah Be-dar ("the thirteenth outdoors," Nowruz day 13), where the prefix si is the multi-of-three. In daily speech, se sotun ("three pillars") is a common cooking-portion size, and se ruz ("three days") is the typical mourning period after a funeral.
