tam

A tam is a soft, round cap with a narrow band and a full top. It is most strongly linked with the Scottish tam-o'-shanter, a traditional bonnet that may be plain or patterned and is sometimes finished with a pompom. For example: "She wore a plaid tam tilted to one side," or "He pulled his tam down as the wind picked up."

The word is often treated as a shortened form of "tam-o'-shanter." That longer name became well known through Robert Burns's 1791 poem, and over time it came to refer to the traditional Scottish cap itself. Because of that history, many people still hear "tam" and first think of Scottish dress.

But the meaning is not limited to Scotland. In modern English, "tam" can also mean other soft, round caps that have the same general shape, especially in fashion. In academic clothing, a tam is a soft academic cap, often worn by people earning advanced degrees. These versions may be made from velvet or other formal material and may have a tassel instead of a pompom.

In fashion, a tam is similar to a beret, but it is often fuller, softer, and more gathered. Some people also use the informal word "tammy," though that is less common. The exact shape can vary, but the idea is usually the same: a soft round cap rather than a stiff hat with a brim.

So whether you are talking about traditional Scottish clothing, a cozy knit hat, or a formal academic cap, a tam is generally a soft round cap with a full crown and a distinctive, classic look.
