A kippah, kippa, kipoh, kip, kepah(/kɪˈpɑː/ ki-pah; Hebrew: כִּפָּה‎‎ or כִּיפָּה; plural: kippot כִּפוֹת or כִּיפּוֹת; meaning "dome"), Yarmulke (the Yiddish term) (Listeni/ˈjɑːrməlkə/ yar-məl-kə or /ˈjɑːməkə/ yah-mə-kə from Yiddish: יאַרמולקע‎, from Aramaic ya'ar malka (יאר מלכא), fear (reverence) of the king i.e. God), or koppel (Yiddish)[1] 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 at all times. It is usually worn by men and, less frequently, by women (in Conservative and Reform communities) at all times. In the United States of America, most synagogues and Jewish funeral services keep a ready supply of kippot for the temporary use of visitors who have not brought a kippah.
