A yarmulke, also known as a kippah (Hebrew: כִּפָּה), is a traditionally worn Jewish head covering. The term "yarmulke" is of uncertain origin, possibly derived from the Aramaic phrase yarei malka (Hebrew: יראי מלכא), meaning "fearing the King" or "in awe of the King," referring to God. In Hebrew, it is commonly called a kippah, which simply means "dome" or "skullcap." In Yiddish, it is often referred to as a kipel (כיפל). The yarmulke is typically worn by Jewish men during prayer, religious services, and other significant occasions as a sign of reverence and respect. It serves as a reminder of the presence of God above. The practice of wearing a yarmulke is observed by many Jewish communities around the world, although the specific customs and styles may vary. For example, in Orthodox Jewish communities, men often wear a yarmulke at all times, while in more liberal communities, it may be worn only during religious services or specific rituals.
