skullcap

A skullcap is usually a small, soft cap that fits closely on the top of the head. People wear one for different reasons, such as religion, warmth, comfort, or tradition. In Jewish communities, it is often called a yarmulke or kippah. In Catholic settings, clergy may wear a similar cap called a zucchetto. You may also see thin knit ones worn under helmets or in cold weather.

The word is also used for a plant. Skullcap is the common name for a group of mint-family flowers called Scutellaria. So in everyday English, the word can point either to a close-fitting cap or to a plant, depending on the context.

The term "skullcap" usually refers to a small, brimless cap that fits snugly over the crown of the head. It has been worn in many places and periods, sometimes as everyday headwear and sometimes for a special purpose. In older paintings and historical writing, you may see scholars, workers, or soldiers wearing one for warmth, comfort, or simple custom.

In modern English, the best-known meaning is often the religious one. A Jewish yarmulke or kippah is a type of skullcap worn as a sign of reverence and religious identity. In the Catholic Church, clergy also wear a skullcap called a zucchetto. Different groups use different materials, colors, and styles, from plain knitted versions to more formal velvet or satin ones.

The word can also describe practical headwear outside religion. Cyclists and runners may wear a thin skullcap under a helmet to keep warm or manage sweat. Similar caps also appear in medical or work settings, where a close fit is useful and comfortable.

There is also a second meaning that has nothing to do with clothing. "Skullcap" is the common name for plants in the genus Scutellaria, part of the mint family. These flowers got the name because part of the blossom was thought to look like a tiny helmet or cap. So when you come across this word, the context matters: it may be talking about headwear, religious practice, practical gear, or a flowering plant.
