A kippah (/kɪˈpɑː/ ki-PAH; also spelled as kippa, kipah; Hebrew: כִּיפָּה, plural: כִּיפּוֹת kippot; Yiddish: קאפל koppel or יאַרמולקע Yarmulke) is a brimless cap, usually made of cloth, worn by Jews to fulfill the customary requirement held by orthodox halachic authorities that the head be covered. It is usually worn by men in Orthodox communities at all times. Most synagogues and Jewish funeral services keep a ready supply of kippot.
