I also know there is another word for it as well. I would appreciate any help you may give me. I am not suppose to get any help from my parents for this project. In America, many people call it a skullcap. They wear this out of humility and respect for Hashem.
Yarmulkes come in many shapes, colors and designs.
Normally, on Rosh Hashanah, Yom Kippur and Pesach, Jewish men wear white yarmulkes. This represents purity and righteousness. The Torah does not command men to wear kippahs, it is a custom. Some men only wear a kippah when saying a blessing, when praying, when studying, etc. Normally Jewish women do not wear kippahs.
