Having an uncovered head; not wearing a hat, hood, or crown.
From 'bare' plus 'head,' a compound that has existed since Old English times to describe someone without head covering, which historically meant exposure to weather and loss of protection.
In medieval times, going bareheaded was a sign of either poverty (you had no hat) or dramatic rebellion against social norms—which is why some religious orders made it part of their vows.
